This feature was planned being aware of this problem.
It does not work currently, GDB just puts the breakpoint on a random first
place found.
The Tom's multi-location breakpoints patch (archer-tromey-ambiguous-linespec)
is being coded with this behavior so that by default gdb syntax it is defined
the first resolution is final.

I would guess this patch should be checked-in only after Tom's. Or make it
opt-in configurable. Or just say the already broken behavior is now broken in
a different way.
Thanks,
