2 ways to look at it

The math on how much more you will get paid coming back early vs 50 hours

Or if you come back early, you can fly your first 50 hours for free each month, money you were guaranteed to still get while at home

I personally chose the latter view on it; resizing if I would go back early, I would get 3 4-day trips and then realize the first 2 trips pay the same I would get at home, and only “in the money” on the 3rd trip
