His straight right. When he has you on target it is very difficult for opponents to move away from it.
What Sergey is doing is throwing a basic 1-2-1, but where the genius comes in is how he determines which shot to load up on. If he throws 1 and based on feel/positioning, he thinks he can land a powerful 2 he loads up on 2. If he throws 1, doesn't feel he can land 2 with tremendous power, he still throws it at 50%, then based on how the 2 felt when it landed, he decides whether or not to load up on the final 1. This is where he's especially dangerous, and what sets him apart. He is often LOADING UP on the final 1 of his 1-2-1's. Not everyone can do this, you need to be ambidextrous and get great leverage. His opponents feel the 1-2 and are so used to absorbing that combo that they relax ever so slightly. The only other fighter I've seen LOAD UP on the final 1 of a 1-2-1 is Rigo when he knocked down some Mexican guy in the 12th. Beautiful
