After a short investigation it turned out, that horizon overrided GLARE_API_URL so both regions went to same GLARE — no wonder the packages showed in both regions =)

Well, it's obvious installation problem. need to remove filling for this parameter from devstack plugin.

    Remove set GLARE_API_URL for horizon

    In multi-region, only have one horizon, so we can not
    set GLARE_API_URL parameter for horizon.
