Iworked for Brintons carpet and Ryalux carpets for 26 years as a sales agent and have inspected more pile reversal complaints than i can remember.
This  can occur in Axminster Wilton Tufted coir matting etc. It normally occurs during the first 3 months after fitting and does not need any foot traffic to make it happen.
One instance i remember well was a site visit 2 a new flat development in Bromsgrove that consisted of 3 flats built on top of each other. The developer had used the same 80/20 velvet pile carpet throughout.
Now if you imagine the 3 flats as a big cake and cut a a pattern from top to bottom with a knife you would leave the same mark through each layer and thats just how the pile reversal affected each of the 3 hall ways on each floor.
I also spent many hours with Ian Hardiman of kidderminster who came up with the theory of D C current within the home and force fields causing the effect. He could be blind folded and walk over a carpet with dowsing rods and find pile reversal every time.I truly believe this to be the cause of the problem but finding a cure is much harder.
Ian went on to invent the Nutralec plug that can reduce the effects of these force fields

Interesting.
Going off that theory then, if you had pile reversal, then changed the carpet, it seems reasonable to expect the same thing to happen again in the same place.
We have pile reversal between the living area and the dining area of our carpet. I never noticed it on the one we had before.
However this could well be because the two carpets are very different, the old one had a week open pile whereas the new one has a deep denser pile of different fibre.
It does seem to make more sense than the reason of 'in built tensions' during manufacture.

Now that I remember, My friend has pile reversal on her lounge carpet, and the carpet before that also had pile reversal on the exactly the same place.
