I don't pretend knowing behaviour of all platforms supported by FPC, but 
I don't think that it should happen. However, you don't show the end of 
the repeat until cycle - depending on the exact condition there, the 
check might be relevant for the repetitions (not that I'd expect it, 
just for completeness sake).
