The else suite is not invoked because that's the way Guido intended it ;)
It was designed for sitiuations like the following:

for beast in animals:
    if is_it_a_cat(beast):
        print("There's a cat among those animals")
        break
else:
    print("Sorry, there aren't any cats")
print("I've been looking for a cat") # you don't need an else for that

i. e. it's only invoked if the loop terminates normally (no break, and of 
course no return or exception).
