His profile should load up just fine. The only potential issue would be if he was licensed for TTK on his XB1 and your boxes weren't, but even in that case it would just limit his activities while he was on the 360.

There's also the issue with junior's friend griping about the 360 graphics nonstop and the peer pressure that creates. But I don't think that was what you're asking about. ;-)
