You wouldn't technically "re-collide" because the collision only occurs if you weren't already touching the terrain. However, I'm currently leaning toward your interpretation that you cannot move through terrain.
The only way to move through terrain would be to enter it on one turn and exit it the next turn. If it doesn't have enough capacity for your unit, then it is a barrier to movement.
