It's a clever way to overcome the the kro of some keyboards. Say you have 2 6kro keyboards (meaning you can't press more that 6 keys at once), together they form 12kro. Playing with 1 hand each allows you to press 7keys simultaneously, something you couldn't do before.
I used to do that when i played on membrane, it's a big reason why I'm comfortable playing with both my hands far apart from each other (thus why my controllers are set up that way). I don't see how a keyboard would lose it's hold to the desk, there's anti-slip material under keyboards :/ I guess it would depend majorly on your setup, but it shouldn't be any different than playing with one.
I wouldn't say this is "recommended", more like a viable solution to overcome KRO limitations
