I think stashes are tagged with the branch name somehow? When I do a `git stash push && git stash list`, I get something like `stash@{0}: WIP on {branch}: {hash} {commit message...}`.
The message you get is an automatic message filled by Git when you don't provide one with the -m option.
Stashes are kind of sort of like branches themselves [1], but they are usually seen as a list, from which you can (cherry-?) pick arbitrary stashes with the apply or pop command, just name it [2]
