Yeah but that (arguably) means he's even more comparable to a left-arm wrist spinner. Murali was essentially a wrist spinner (he certainly generated the turn of one anyway), whose stock ball turned into the right hander but could also turn it away, which pretty much fits the description of a chinamen bowler. Apart from using the other arm, of course.
I think the best explanation of why there haven't been any world-class chinamen bowlers is simply how difficult an art wrist spin is. When you look at how few world-class legspinners there have been and factor in how much of the population is right handed, it isn't altogether unsurprising that there has never been a world-class chinamen.
