I suppose it's possible to empty the 13 on a deep cave dive with lots of ups and downs. It's one of the reasons I have an inflator hose on all my bail out or stage bottles, bungied to the tank.
*taking that one a step further off topic. Keep in mind that rebreather dil and o-2 cylindars are only 19 cubic feet so be careful with the CCR's the first few times you try to cave dive with them. Check that dil pressure frequently!
