Yes, Python sees imports of two different absolute module paths and does
not recognize them as being the same file, so it imports each separately.
This scenario typically arises when your sys.path includes a folder that is
actually a module itself.  Recommended usage: don't do that.  Your sys.path
entries should contain modules and packages, not point inside them.
