Monk slammed Moses over the way he won a penalty in Sunday's defeat.
Bowen told Radio Wales: "To call a player a cheat is totally out of order because there was contact there.
"Is Moses trying to make the best of a situation? Yes. Was it harsh on Swansea? Yes. Was the decision a poor one? Possibly yes.
"My definition of cheating is if a player goes into the area and he's not touched, if there's no contact and he goes down he's a cheat.
"I don't care if he's my player, somebody else's player, if you're not touched in any way and you go down you're cheating.
"It was very slight... but if there is contact there it's up to the referee to differentiate is it enough to be a penalty or not.
"If we were Swansea and that penalty was given we would be upset, of course you would, because there was minimal contact.
"But to call the player a cheat is totally out of order because there was contact there as that picture clearly shows."
