Did you mean refs/heads/branch-$i here? As it is written, it creates a root ref, and the name does not conform to the usual rules (all-caps, and ending in _HEAD). There are some holes in our checks, which is why it doesn't barf yet, but I have a series to fix that which I hope to send out later this week.

Arguably this verify command should be complaining about the broken names, too.
