Why is this the result of this python program?

Question

Someone from #python suggested that he search for the "herpaderp" module and find all those listed as a search. If so, why doesn't he list every module in my system before raising an ImportError? Can someone shed light on what is happening here?

import sys

class TempLoader(object):     
    def __init__(self, path_entry):
        if path_entry == 'test': return
        raise ImportError

    def find_module(self, fullname, path=None):
        print fullname, path
        return None

sys.path.insert(0, 'test')
sys.path_hooks.append(TempLoader)
import herpaderp

output:
