Python Programming: Multiline Comments before an Else statement

I was working with simple if-else statements in Python when a syntax error came up with the following code.

"""
A multi-line comment in Python
"""
if a==b:
    print "Hello World!"

"""
Another multi-line comment in Python
"""
else:
    print "Good Morning!"

This code gives a syntax error at the "else" keyword.

The following code however does not:

"""
A multi-line comment in Python
"""
if a==b:
    print "Hello World!"

#One single line comment
#Another single line comment
else:
    print "Good Morning!"

Could anyone tell me why this happens? Why does the Python interpreter not allow multi-line comments between if-else statements?
