"Soft", like a mushroom, toadstool, leather, etc
"Hard" usually refers to corals with calcified skeletons, like the "SPS" types of corals. And yeah, since they are hard skeletons, all they do is retract their polyps in when they want to and the branches themselves remain the same. Is that what you're looking for explanation-wise?

Read the Renaming our Corals article on the homepage

Has some great information into naming corals. Soft Corals generally do not have any hard Skeletons. By hard we really mean hard to the touch. They break and crumble when bent. They do not change sizes during light cycles. The tiny polyps will extend or retract when touched. Soft coarls will tear when bent and are essentially all soft tissue.
