The only time I had liquid enter my line was when I had the gas tube on the bottom, keep the gas tube at the top when you rock and roll and you'll be fine.
You should have a pretty good pressure buildup to stop liquids from coming up the line; although that won't stop excessive shaking from overwhelming the pressure in the gas line. Odds are you have a directional flow valve on your regulator, so you don't have to worry about gas being pushed back. You probably shook the bottle of water hard enough to ...
While it's possible for some to go in that direction, there should be some pretty good positive pressure (especially when it's pumped up for carbing w/ shaking) to prevent anything from going upstream. If your system is designed well, the valves will have flow restrictors that allow only gas to leave the regulator... aside from whatever might get stuck in ...
