I think it looks rather shmexual. And come on, guys- he's obviously put the pickup switch there because he knows he can utilise it best there. You don't get a custom guitar and specify the switch to be somewhere random on the body, or just for the hell of it- he's got it there because he'll feel comfortable having it there when he's playing.
And to be honest, I reckon it's probably in a better place than down at the bottom near the controls- to switch pickups you just have to reach up slightly from the strings instead of lunging down below the tone control. But hey- it's horses for courses, I guess :D
