This information is probably not all that useful.  Obviously the
packages will provide the same dependency; that's (in part) why the
packages have the same name aside from the architecture.  In this
example:

If a 32-bit program were to try to link with the 64-bit glibc (or
vice-versa), all sorts of problems would result.  To remove
glibc.i686, you'd have to be sure that there were NO other 32-bit
packages on your system.

I think what you're really looking for is the set of packages that
appear in your previous rpm listing as duplicates, but that DO NOT
appear in the deplist output at all.  The packages that DO appear in
the deplist are presumably those that you need to keep.
