My pleasure, Ralph.
I have to admit I'm not a Plath fan at all, so I'm unfamiliar with your Plathian reference above, and to whether it fits the bill or not.
But no, they don't mean the narrator of a well-known poem. Have you looked at the LitRev 'Clairvoyance' thread? The winning poem this month alludes to 'Albert and the Lion'
here and what they're after is a similar idea i.e. find a famous poem
about someone and then write your own poem alluding to it (I think!)
I hope that makes sense and I've made it clearer
