Yes: name-tag-list defines the precise name tag to use for a given 
object and so interacts with any style rules that match that object and 
also use the name tag for labelling purposes.

There's no easy answer if you're making a global map that has to have 
some sort of consistency.  This is the first time that I've seen an 
operator:en tag and there's no way to account for it using 
--name-tag-list.  The only way to fix it is to use a modified style rule 
that uses operator:en in preference for operator.  This could be a 
change to the mkgmap default style, but if you do it for fuel you'd 
really have to do it for all rules to avoid a special case.

Preferable would be for the --name-tag-list code to be made more generic 
so that it applies to any tags, not just name.

I think the default one is probably the best generic stylesheet out 
there that doesn't require a TYP file.
