Pretty much how it works by Klutz's model.
So two ships that both collide on the sides, one is touching and one isn't. Two ships that move (and collide) at the same PS, one is touching and one isn't.
This is why, IMHO, the Stationary ruling is what it is. It's a guess, of course, but otherwise you get crazy hard-to-reconcile situations like that. I'd honestly welcome an overhaul the whole "touching" mess, but since we aren't likely to get that I'll be happy with a nice, clean, "overlapping creates touching which lasts until one of the ships actually moves". Whatever logic makes it a good ruling for stationary maneuvers should apply equally to a no-movement blocking situation.
