  In what sense is that "wrong"?

  What do you mean by "wrong"?  Soft-links are text strings, they cannot be
inherently "wrong" or "right" unless you have some extra criterion to apply.

  It's an interaction between two things:

1.  /bin and /usr/bin are the same physical directory, /usr/bin being a
mount point for /bin.

2.  exe magic only works on links when they can be resolved.
