Cyclic reference

[Uchikago]

Hi, today i came across this code:

#test1.py 
x=1
def change(): 
    import test1 
    test1.x=2 
change() 
print(x)

output is:

2
1

I want to ask why this doesn't make a cyclic reference, since change function import a module have the function itself. And also, it's output should be 1,2 instead of 2,1 right ?
