Did he actually _miss_ it? I don't think it's that hard to see as there aren't
that many moves to analyze there and I can't believe a GM simply didn't consider
it with his king exposed that way. I just presumed that he expected 11...fxe4+
as that is the obvious materialistic/computer move: grab everything you can. He
himself said that he tried a bit of anti-computer strategy so I concluded he was
also thinking along the lines of what computer moves to expect, as naive as this
may seem to those in the know.
