BUT, I've never arrived at MCO internationally, so I'm not sure where passengers are dumped off after passing through US immigration.
They are normally taken to the main terminal, I don't think there is an option to remain in the concourse. You would have to reclear security, assuming they would even let you back into that concourse without a boarding pass for those gates.
