To be safe you could alternate the ring direction, as that is the way wide panels are supposed to be glued up according to wood technologists. If I'm working with a fairly stable wood and do a 2 pc body with routs to cut into the wood, I glue them together as you are showing in the pic. That make the top surface the one where you see the rings as smiles instead of frowns. That way any cupping keeps the bridge and pickups more or less in the same plane as opposed to the other way around where the sides would pull upward. I've never heard any complaints from anybody about movement. I also rough plane and joint and let the wood sit overnight before gluing it together allowing stresses to move the wood if it needs to.
.....That's All Folks!.....
