Hugo's explanation is nice and clear.
You may also want to look at this way
Consider the most simplified form of the issue
def alpha():
if X:
beta()
else:
return q
Here in the*if branch* nothing is returned
None is returned, not nothing.
while in the *else branch *something is being returned.
That is whenever X is True nothing is returned from alpha().
Even if beta() returns something that is not being used.
But when X is False something (q in this simplistic example)
is being returned
So this is a bug.
