I think an overbet is getting called by a wider range of hands than the bet OP made. Combined with a turn check/check, an overbet looks like a bluff. Why would you overbet for value into someone who has shown no strength?
Yeah, I know you can think about the levels forever, but in general overbets get less respect than bets that look like value bets, and in this specific situation I would not expect an overbet value bet into someone who checked behind on the turn.
