Oh no, the stuff I put in quotes was not Robbi speaking during the hand, but my imagining of what Neganeau would have sounded like in his typical confident chattery thinking aloud.
My sense is that the different reaction would be because of the narration, not the identity of the player (though it would also make sense that a player with a decade(s) long reputation would be given more deference than a newer player).
I think the reality is she just made a shitty decision in the moment that happened to play out well. Anyone who's played poker long enough has done the same dozens of times.
