Basically my take on their whole conversation was that i think Ichigo was just telling Mayuri that he knows Kisuke was his former captain, and that one thing Mayuri probably doesn't want is to make the guy who gave him a shot at something more then just entrapment, be dissappointed in that decision. I mean i think Mayuri really does respect Urahara, and anything he does, and sometimes wants to mirror what he does to a T. Regardless of how upset it makes him to be talked to as if he is similar to Urahara, one reason i think Ichigo made that comment was so Mayuri knows that this is serious, and all his talk about "locking them in there" is something that Urahara wouldn't want.
