If you keep tank topped off you have no room for expansion and contraction to draw in outside moisture which can condense inside the tank. you also don't have the small amount of gas that's left going bad, the large amount takes longer to go bad. If the small amount drys out it can leave deposits which can float in the next batch and clog up your system.

There's nothing particularly bad about the drain it dry program.
The fuel won't go bad in one season. Also far less work to store it, saves time and huffing gas fumes. If you get a random storm after you've put it up, you can just take 5 minutes and do it again.
