Why does git stash create 2 commit objects? It seems 1 was adequate

Question

When executed git stash, 2 commits are created. One of them refers to stashref and has 2 parent commits. One parent is an index of where we made the cache. The other parent has the actual content of what we hid.
Why does a wallet require 2 fixes? It seems to me that only 1 was enough. That is, just do a stashref for the commit having the actual contents.
Would it work?
