Well, that's the correct behaviour, that's what RPM is for after all.
If you uninstall the library, the programs in MyPackage will break, so
the only way to (cleanly) uninstall the library is to uninstall
MyPackage first.

Yes, add "AutoReqProv: no" (syntax may not be 100% correct here) to
the specfile.

Or uninstall MyPackage, since it will be broken after you install the libraries.

Basically, it does an "ldd" (actually "objdump" which is a more
powerful "ldd") of the binaries, which will list to which libraries
they are linked.
See this script for more details: /usr/lib/rpm/find-requires
