If you've encountered this situation (and seen it happen to others) then that is more than my conjecture. I've got into the MLL 3+ hours ahead of time but I'm always on an actual connection, am SE, etc. and I have never been asked for an inbound BP so I don't know for sure and I am guessing.
But I would argue that it is neither in the letter of the rules (this is not a "connection" as far as AC is concerned so subject to the 3h rule, and the domestic MLL would be an arrival lounge not a departure lounge) nor in the spirit of the rules regarding lounge entry.
