That doesn't really imply much. Having a fifth rook does not correlate at all to having a piece of the same or opposite colour. Regardless, based off that rule, a piece of the opposing colour would be defined by "any other peice [sic] which he may deem more useful for his attack" in that play, so it sounds perfectly legal to me.
