Problem with some code

def checkio(text):
    count=0
    for x in text.split():
        if x.isalpha():
            count += 1
            if count ==3:
                return True
            else:
                return False

There is a problem in this code.It returned true before adding the last else statement when I passed ("Hello World hello") but when I added the the (else) it returned false and didn't work.

Can I know how to make it run properly and the reason for the problem?
