They’re mixing and messing definitions and concepts and separation together and then get confused because of it. It describes a behavior analysis discovery but lacks the useful, valid discovery. I don’t think this is useful for others to read, and detrimental for git newbies, because it’s more difficult and confusing than helpful.
git says HEAD defines the current branch
rebase is a process operating on commits and branches - it breaks out of the simple “current repository state” because there’s a process and process state around that. They notice things being different, but fail to elevate their view or discover that they have to interpret it differently.
bare repository has no workspace - as such, workspace commands won’t work, and there is no workspace current branch. HEAD defines the default/main branch.
And they never ger into the got worktree subcommand and probably don’t know you can have multiple things checkedout at once in a different Dir but still all pointing to the same local git clone.
Also with them you can have a bare repo with multiple worktrees at once. Have been working this way for a few months now and it is very nice when switching branches as that becomes a simple cd instead of a git switch or checkout. Which means you don’t need to stash any pending changes before you switch branch.
