The only possible line here if he was thinking is if he knew his opponents would nearly always bet with a A or K and might bet at the turn but would fold to a raise - so he wasn't hoping for c,c,c; c,c,b,f,f - he was hoping for c,c,c; b,c/c,b, r,f and the actual action was indicative of him failing to get an extra bet out of the situation.

But you'd have to know your opponents to try this parlay and if the elements aren't there it isn't a particularly good line unless you just figure check,check means they missed and you can use this opportunity to mix up your game/image without having too much to worry about losing bets.
