Well the possibility of Gintoki not actually "bending over" Madao is still there :.
The part in the manga that was not shown in this episode from what I can remember is the part after where Sacchan jumped the Gin clone where she pretended as though Gin clone was touching her. Then there's the part at the end where Otae goes on saying about how drinking is bad while Shinpachi pointed out that a girl working as a hostess shouldn't be saying that. Lastly, and this part was the funniest in the manga, the part where the guy yelled out "YUKIKOOOOOO!!" whenever Gin clone touched him and Gintoki getting the feeling that the guy knows deep down that his girlfriend isn't the one touching him
