The problem is when dpkg-shlibdeps can not determine the correct 
dependencies on library packages (e.g. a versioned Depends) and the
package maintainer added an explicit 'Depends: libfoo (>= 1.2.3)'
to the control file. Unless the source package is changed , the 64 bit 
binary will end up with 'Depends: lib64foo, libfoo (>=1.2.3)' instead
of the correct 'Depends: lib64foo (>=1.2.3)'.
Luckily, these seem to be far less common than I first though, so
it could still be possible to do them by hand.
