That works, why?

Well, it is perhaps a bug in dpkg that architecture-qualification is
required for a foreign package that is not 'multi-arch: same'.

But what about foreign 'multi-arch: same' packages?  I would expect dpkg
to always require arch-qualification for them, even if there is a single
installed version and it's foreign (e.g. for cross-development).
