Instead of Nakamura why not his opponent live right now?

https://en.wikipedia.org/wiki/Pavel_Eljanov
Nakamura vs Eljanov started 30 min ago
https://chess24.com/en/watch/live-tournaments/baku-world-cup-2015#live
Some evidence:
http://www.chessbomb.com/arena/2015-worldcup/04-3-Jakovenko_Dmitry-Eljanov_Pavel (look at first 6 moves and compare to our game)
Exact same opening today in Nakamura vs Eljanov except he played Bd7 instead of Nbd7 on move 5?
If he afraid Nakamura is reading this thread and getting all his ideas (and switched his 5th move to throw him off)?
Will many GMs start following this thread now?
WTF!
