If you have a splitter with a 50A male plug and two 30A female sockets, you can use it to plug two 30A RVs into a single 50A outlet, and both will have ample power available (assuming decent campground infrastructure).
If you have a combiner with a single 50A female socket and two 30A male plugs, in theory you can plug it into two 30A sockets and get more power than with a single 30A to 50A adapter. I personally would throw the Y cable out, however, as there are a number of potential problems inherent in the setup. It will not work if either of the sockets you're plugging into has a ground fault interrupter as it by design creates a ground fault. If one of the sockets has a poor or broken neutral connection and both are on the same phase you could have a substantially overloaded neutral connection on the other one. If one of the sockets is badly miswired with swapped neutral and hot leads, plugging it in will create a short circuit that (one hopes) trips the breaker on the power pedestal. There likely are other fault modes that could be dangerous.
