Six years to get an answer!
Nothing is wrong with 22 Nxe5.
I tried 22...Bd6, but it doesn't work, because of 23 Bxf7+ Rxf7 24 Nc4 and the tactics are better for White.
My silicon friend found 22...Rbe8, which complicates the position, and may be the reason 22 Nxe5 was not played. 23 Bf4 Qd4 24 Nxc6 Qxe4 and Black at least has some counter-play.
Bagirov's 22 h3 has the advantage of simplifying the position by trading off pieces, which is probably a good idea against a tactical wizard like Korchnoi.
