Well, the episode dialogue does state that the Neutral Zone is "between planets Romulus and Remus and the rest of the galaxy," implying that it's only that one planetary system that's interdicted. The map graphic, however, paints a different picture (literally) by referring to the "Romulan Star Empire," drawing the NZ as a roughly linear band instead of a circular cordon, and dotting the map with stars so as to imply it spans dozens of parsecs. Most of our subsequent assumptions about the Romulans, both in canon and elsewhere, are predicated on that graphic rather than the episode dialogue, which never mentions an empire. (The existence of a Romulan empire wasn't established in dialogue until "The Deadly Years," and then "The Lorelei Signal.")
So I'd say the scriptwriter and the map artist were definitely not communicating clearly. Understandable, since the map would've been created weeks later in post-production. It's the same kind of conceptual mismatch as the animators showing torpedo-like blips when the script specified phasers.
