Yes, a record armed track will put that track into live (low latency) mode and also reserve one thread for it. Which is also why you usually select a "no output" or record disabled audio track in case you want to squeeze out the last ounce of juice. That way, the core can be used for playback tracks as well (at least most of it - apparently a certain amount is still reserved for whatever it might be).
As far as the activity monitor's CPU meter goes, I don't think it's lining up the CPUs properly - maybe Apple hasn't worked on that yet.
However, the video you've posted clearly shows there's nothing fundamentally wrong with Logic, possibly with the exception of Alchemy (Diva might not even be fully supported yet, hence running in Rosetta mode). And as far as Alchemy goes, who knows, it might be because the Camel Audio folks are still maintaining it - so maybe they're just late or something (whereas Scuplture is a genuine Logic synth).
Would like to see a variety of different tests, though. I was about to prepare a singlethread test - but that was using Alchemy. So I rather modify it and use Sculpture, too.
