I don't think it is either, but keep in mind that dude is a fake natty faggot, so you have to be on gear to look like a roidtranny retard anyway. I hit arms twice a week as an accessory with preacher curls and then it's utilized in various compounds. I do however hit triceps every single day though.
I think in general it's never good to hyper focus on anything too much, like you never want to have giga retard quads to the point they make your torso look tiny, just my opinion thiugh. Only thing I hit hard every session is lats and that's because it's a problem area for me
