If you were going to hang the camera on a branch, I'd hang it under the branch (if it's atop the branch and it starts to go, it'll pick up speed as it falls and perhaps have enough momentum to flex free) and find a way to safety it, either through a detachable neck strap, a safety cable, or perhaps just running the neck strap over the branch and clipping it back to itself.
Here's a sample of the gorillapod holding a flash just out of view on the boat:
The gorillapod was wrapped around a nearly-horizontal pipe (the 'bimini' or sunshade that's in portions of the image) and held the flash horizontal (i.e. it had a lot of 'twisting' forces) for hours. Canon 580EX II flash hung, 580EX II as trigger, 1D Mark III with 16-35/2.8 (that needs to go in the shop) at f/4, 1/2500 at ISO 100; ambient at -2/3EC.
