The [keystone]/region_name config option in nova is used to pike the 
identity service endpoint so I think in that case region_one will matter 
if there are multiple identity endpoints in the service catalog. The 
only thing is you're on pike where [keystone]/region_name isn't in 
nova.conf and it's not used, it was added in queens for this lookup:

So that might be why it doesn't seem to make a difference if you set it 
in nova.conf - because the nova code isn't actually using it.

You could try backporting that patch into your pike deployment, set 
region_name to RegionOne and see if it makes a difference (although I 
thought RegionOne was the default if not specified?).
