Can we get a grammarian's ruling on that one? I don't think it's right. For example, consider the following sentences:
The Pokémon master Ash Ketchum started his adventure with only a single pikachu.
Ash Ketchum, the Pokémon master, started his adventure with only a single pikachu.
In the first sentence, 'Ash Ketchum' an appositive the modifies its preceding phrase. It is an essential or restrictive modifier - it tells us specifically which master we're talking about. Since it is essential, it is not set off with commas.
In the second sentence, the order of the subject has been switched so that the appositive phrase is 'the Pokémon master'. It is an inessential phrase since the sentence retains most of its meaning without it. In English, inessential modifiers are usually set off with commas.
Returning to the example used in the picture, 'JFK and Stalin' is an essential appositive phrase. It tells us specifically which two strippers are being talked about. So I don't think it should be preceded by a comma.
I should probably get more sleep.
