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
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.
