That's not surprising, but there isn't a warning. IMHO, finding
several branch matches is a strong indication that it'll be worth
reporting to the user that the DWIM machinery got hits, but couldn't
work it out.

I get that process is not geared towards making a friendly msg easy,
but we could print to stderr something like:

 "branch" matches more than one candidate ref, cannot choose automatically.
 If you mean to check out a branch, try git branch command.
 If you mean to check out a file, use -- before the pathname to
 disambiguate.

and then continue with execution. With a bit of wordsmithing, the msg
can be made to be helpful in the various failure modes.

cheers,
