The phrase in the policy would also allow a conditional recommends or
depends to packages outside main.  As long as the dependency or
recommend can be fulfilled with a package in main, it should be fine.
This is the relevant section from the policy.

  2.2.1 The main section

  Every package in main and non-US/main must comply with the DFSG
  (Debian Free Software Guidelines).

  In addition, the packages in main

   - must not require a package outside of main for compilation or
     execution (thus, the package must not declare a "Depends",
     "Recommends", or "Build-Depends" relationship on a non-main
     package),
  [...]
  Similarly, the packages in non-US/main

   - must not require a package outside of main or non-US/main for
     compilation or execution,
  [...]

A package declaring 'Depend: package-in-main | package-not-in-main'
would not _require_ a package outside for compilation or execution,
and would thus be just fine working with both.  Similar for
'Recommends'.  The relationship would thus just be documenting the
fact that both a package in main, and package outside main, can be
used together with the package in question.
