Currently, a mass replay check will indeed continue running beyond the level's save requirement in case continuing further will earn a talisman (or as of 12.10, set a record - prior to this, mass replay check did not update records). This talisman in turn will indeed be unlocked correctly, however, in terms of the replay results list, the replay will simply be marked as a normal "pass".
I'm proposing that talisman-earning replays be specifically distinguished from ones that pass but do not earn any talisman. It may be worthwhile to ignore "complete the level [with no further requirements]" talismans for the purpose of this, though.
