after camping on an “external” cell, the MS will select a cell from its own network only if it totally looses the “external” coverage, or after IMSI DETACH/ATTACH or after manual reselection.
Maybe some MS’s can automatically check if their own their primary network, but I don’t think that’s in the standards.
