When you said earlier:
Maarten De Queecker
[They] don't know the right path to take in order to receive a technique painlessly. On the contrary, they will try to stay away from that path .....
I thought this could mean, alternatively, not moving or moving along a path that leads to more pain and discomfort (for example, from nikyo).
It also seemed to me one reason to move the wrong way might be, as you suggested, to resist.
I also think newer or untrained people sometimes move along the wrong ukemi path because they are trying to escape pain, but either don't know how or, in some cases, simply can't move in the way that minimizes pain (yet).
