"Why didn't the interpolation code complain that TOP was undefined?"

Because we developers are horrible terrible people that want to cause you
pain.

I would ask what version of Ansible you are using and if undefined variable
detection is turned on.  If on, I would expect this to result in an error,
and if not, filing a github ticket would be a good thing.

Thanks!
