Fighter Movement Bug?

I've noticed something in my current game that I've been using to great effect but I'm not sure if its a bug or a feature.

I have a fighter squadron, movement 22, going from planet A to planet B 12 hexes away. I land the fighters then immediately re-launch in the same turn. How much movement should they have left in the turn? Instead of coming back up with the remainder of 10 they re-launch with the full 22! So, in one turn I can literally fight multiple battles anywhere in the sector and still have enough movement to move elsewhere, do anything, and still end the turn guarding a warp point. I'm loving it but it just doesn't seem right.

Just fixing this would make fighters less powerful.
