From what I have experienced up to now the conditions of the problem are:

1. the unit has done full move (0 move points left)
2. The units is suppressed and pinned
3. The unit has received op fire

For instance, once one of my unit has destroyed an enemy ammo depot and it has received casualties from the secondary explosion while at the same time other hostile units have also received casualties. The result of all this was the return of my full move points.
As you can read no rally operation was effectuated but still my unit has gained the full move.

My impression is that this issue is connected with a positive morale check while the unit comply with the previous mentioned conditions.

Anyway, this reminds me of a similar "BUG" condition in another SP variant, where the gamey tactic (in order to make a unit "fit" to move) was to shoot (Z-fire) at your own pinned or routed unit.

cheers,
