It's not *how* IDLE imports the module, but that fact that IDLE imports the 
module before his script would be executed. For example:

### sys.py ###
path = "Hello"
############

### test.py ###
import sys

print sys.path
############

Save sys.py and test.py in the same directory. Run test.py from the command 
line. Then open test.py in IDLE and run it in IDLE. You should get two 
different results because IDLE imports sys as part of it's own code and 
python does not re-import modules. However, when you run test.py from the 
command line, sys has not been previously imported and our own sys.py is 
imported.

Hope this explains my reasoning.
