question about Architecture: all and Dependencies

[Lorenzo <plorenzo@disroot.org>]

Hello Mentors,

Is it ok to have a package with Architecture: all that Depends: on
another one (from the same source) that is Architecture: any?

[1] says that all is for architecture-independent packages, but it does
not say anything about Depends;
by looking at [2] it seems that Dependencies matters but then I'm not
sure about the difference between Multi-Arch: foreign and
Architecture: all ...
