The above happens to work because origin/HEAD maps to origin/main.
Specifying -b origin/main would be more explicit and prevent surprises
in case the value of HEAD changes (which it generally should not, but
who knows.)

The HEAD symref is only used to determine a default branch to
fetch or checkout in absence of arguments which specify a branch.
This is Got-specific. Git uses HEAD for more things.

If you enable mirroring then 'got fetch' modifies references
in refs/heads directly, so you can skip the rebase in the above
example and just run 'got update' instead. So that step becomes
a bit simpler. However, if you have local commits on any branch
they will now collide with fetched changes from branches using
the same name on server. Recovering from a branch name collision
like that is not impossible but it could be a bit more difficult
than rebasing branches.

I would recommend to enable mirroring only on repositories that
sit on servers and receive changes only via the network, not from
a 'got commit' command.

Without mirroring enabled, branches in refs/heads are yours, and
won't change during 'got fetch', and can be rebased after fetching
as you described above.
