More Questionable Math

[1MoreFish4U]

I wasnt in this hand. After it was over, a player not involved claimed that again it was about a coin flip after the flop. Is this correct?

In addition, in spite of the odds postflop, how many would play to catch the flush with the cards the winner held?

These 2 players had no history, altho the loser is a decent palyer who plays very tight & the winner had been a calling station so far in the session.
