The request was made very politely both times and I didn't even question it (my guest didn't want to stay longer in any event), but I'm not actually sure whether this requirement is specified in the applicable rules.
I didn't know that; they might be more lenient in Galleries Club. I've certainly in the past guested people into the Galleries/Terraces lounge who have been on later flights, and they've been able to stay there until well after I left.
