When multiple hosts are used everything seems to execute on a single host instead of the intended host

[jawnothin]

Describe the bug

If you have two jobs connecting to two different hosts, it issues all the commands against one of the hosts rather than the intended host.

If I do SSH_HOST_1 and SSH_HOST_2, things seem to work just fine ... but if I do what's described below ... SSH_HOST and JOBS_SSH_HOST ... even though the logs show the right IP, everything just goes to SSH_HOST.
