Yea from the video it is Sabo starting it.
Looks pretty innocent though. Still Indoors I'd stop him starting like that and let them go for it outside if it is equal enough.
Fair point, I don't generally let my big dogs rough play in the house and they seem to just play better and get along better in the larger space of the backyard... I've seen more tiffs happen from playing indoors. Of course this will vary by pack.
