IMO, one of the changes they made in 1.27b was to put all launched units in the same group. I'm not sure why they did this but in addition to interfering with the tactic you mentioned, it also introduced a bug into the fighters. (If you launch fighters from the planet, they shouldn't have any movement left. But when the game merges them with a group that *does* have movement, then the whole group including the fighters just launched from the planet have the same movement points as the group.)
