Yes, the git metadata does not hardcode the path to the repo anywhere.
See gitrepository-layout(7) for perhaps more detail than you wanted.

You might want to use "git add --refresh ." (or even just "git diff")
to update the cached stat() information before starting work with the
new worktree, but that only matters if you are going to use very
low-level commands.

Sure, that's a good way to do experiments.

Hope that helps,
