No, I meant the situation where both

    "/" in sys.path

and

    "/package1" in sys.path

are true.  (You can substitute something else for "/". :-)

Tis is really evil, because when you write

    import package1.package2.moduleX
    import package2.moduleX

two independent copies of moduleX are loaded, that don't share state.
