No it's not. People fly on flights other than their bags all the time. If you check in and miss your flight, your bags often get there before you do and might even take a different routing. I missed a Southwest flight from MDW to PDX once. I ended up flying MDW-OAK-PDX, and my bags were in Portland long before I was.
There may be a rule for international flights, but I can't find a source on this. (The "you must use the lav in the cabin in which you are ticketed" rule only applies on international flights, for example. It may even only apply on international flights to the US, not from the US. After all, the 9/11 planes were international flights to the US. Oh wait...)
