I can't disagree with you as I can only state my long meaningless life experience around hockey.
Regular season points means nothing, in playoffs as you can't bring them with you. I'd rather have a well rested team playing an away playoff game than having a tired team playing at home in a brand new season winner takes all series. Just need to know how to play a tired home team in their barn , regular season points does not guaranty home team wins. That's only me speaking with little meaningless life experience of hockey, as I don't know these kids I don'd speak with them on a daily basis I am not around them at all. I am only speculating like everone elses as we all know playoffs hockey can be full of surprises, even at home. Cheers!
