Does Orton have a twitter? Watch for the telltale follow from TH. That's as good an indication that he's involved as a snap of the actual contract.

Is it necessary? No. But looks like they'll do it. As has been mentioned: the greenback talks.

I would guess that, if asked, he'd do it. He doesn't seem to be drowning in work, and it's really his main claim to fame - besides for Marvel and Tayto. Even if it's crap, he'll do it. Mainly because he can't tell the difference between good and bad, and because his talent will overcome all failings of plot, plan and script, e.g., ISTL, Shit Island, Tayto....
