Yes, it is correct (except that the "rebase" is missing, of course). Since A2 is based on A1, you could even use "git rebase origin/A2 B1".

I assume "origin/base" is what you called "origin/A2" above. The output is a bit confusing in this case.
I tried "git rebase [--onto origin/pu] origin/pu origin/master". That printed
Fast-forwarded origin/master to origin/pu.
which is even incorrect. It didn't (and shouldn't) update origin/master, so it obviously shouldn't say that it did either. Should be easy enough to fix. I will have a look at that when I get some time.

It detached your HEAD at origin/A2, but no commits, nor refs would have been changed or lost. You can safely checkout out B1 again if you want.
