Git clone will turn symref B into a regular branch,
which will not move in parallel with A.
People may have private scripts which will
be surprised when they encounter B. E.g. when
parsing the output from 'git branch'.
Check out B, then you expect B rather than A
to be reported as the current branch:
git checkout B
git branch
* A
B -> A> ▶ Are there other solutions?
You haven't explained the problem which led you to want "equal"
branches. E.g. if it's hard to teach developers to switch
from B to A, a hook which rejects pushes to B might help.
Possibly in addition to them using a private symref. In this
case, 'git symbolic-ref B refs/heads/A' might work better.
