I use the PC brushes and have pressure washed mats before. While it has it's place, some caution needs to be used. Judging from the pictures the mat was mainly dirty on the one side and in the picture where it is being vacuumed the dirt is gone. The color of the mat appears much lighter in the last picture. This may very well be just lighting and camera angle and therefore not a problem. The white brush is probably because of the change in lighting and camera angle. The woolite isn't very harsh but the pressure washing and vigorious agitation is which is where I see a problem. This is going to disrupt the pile of the carpet and in many cases lighten the color. Carpet extractors are not moving the volume of water or operating at the PSI of a pressure washer. The white brush is the most aggressive brush for interiors and the 3rd most agressive out of the 4 brushes offered. I have it and the grey brush, preferring the grey brush which is far less aggressive. In the action photo the brush looks to be on 5 or 6. Saturating the carpet with a pressure washer and then using a white brush at a high setting followed with more pressure washing is going to disrupt the pile of the carpet. This can be seen in the last photo. As with polishing start with the least aggressive method. This is not meant as an attack just my 2 cents from experience.
A lot of your post is confusing me, but Ill try to address your concerns.
"Judging from the pictures the mat was mainly dirty on the one side and in the picture where it is being vacuumed the dirt is gone. "
What are you trying to say here?
"The color of the mat appears much lighter in the last picture. This may very well be just lighting and camera angle and therefore not a problem."
The direction in which you vacuum will change the color of the mat. I do this on purpose because it gives a sense of cleanliness. Now if you're comparing the two dark lines to the color of the original mat, then you need to realize the first picture was taken with the mat in the shade, the last was taken in direct sunlight. So yes, it might seem slightly lighter. However, there was no difference in person, except for the fact that it was a lot cleaner.
"The white brush is probably because of the change in lighting and camera angle."
You lost me.

The pressure washing does disrupt the pile of carpet. But then again, so does everything else. The good thing about it is its not permanent. This is also the reason I said to move the nozzle further away from the carpet to get rid of the water lines. Then you vacuum it with the design of your choice. You can do what you see in the last picture, you can make the entire mat lighter, or you can make the entire mat darker. You can even do a checker board pattern if youd like. All of this is disrupting the the pile, but is easily changed. It does NOT change the color of the mat though. If it does, then youve probably just removed a lot of dirt that was making the mat appear darker.

Yes, you're correct, but I think you're over exaggerating slightly. The white brush is not that aggressive/ stiff. The gray brush is VERY soft and doesnt have near the cleaning power that the white brush has. Ive never had a problem using the white brush on any carpet. But if you do, then go ahead and step down to the gray or aqua brush.

Yes, the PC is on speed 6. I already addressed the disruption. But I surly dont see any evidence of it in the last picture.
Justin has been using pressure washers on carpet mats for years and he recommends it whenever someone posts about cleaning mats. Because of that, I assume hes never had an issue either. Ive been using this method for some time and havent had an issue either.
