Well no one else has commented on it, but I don't know how it could not 
be a bug, tho this 'shortloops' must  be there for a reason. Docs refer 
to the 'short form' of various constructs but what's the point of it 
here?  I see the use with 'while', but with 'if' it seems trivial.  I 
see it as just letting me get away with mistakes.

Yes, it's just there as contrast for the questionable one.
