Once the deep radial n. exits the tunnel through the supinator muscles (i.e. supinator tunnel), it changes names to posterior interosseous n. Honestly, I've alway heard supinator is innervated by deep radial n,, but I suppose its possible the posterior interosseous n. donates a few motor branches to the distal portion of the supinator. Just a guess though. If you're on an exam go with deep radial n.

Thanks ❤❤❤
Thank you for the amazing explanation
Great video!!!!
isn't Supinator innervated by posterior interosseous nerve as well?
