Err, maybe I wasn't clear, but I think we're talking about the same 

see if this clarification helps:
"if the button is [in the] pressed [state] it checks the flag 
 [that indicates whether the button was in the pressed state the last
 time we checked] and only does the flap if the flag was cleared
 [(indicating that last time the button was in the unpressed state,
  and therefore this is a "fresh" button press)]"

So it doesn't "do" much on button up, except set the flag 
so that when the button *is* down we'll know it's a fresh buttonpress.
Plus it might change the wing position from down to up.
