"Because nothing can cross the Barrier, and we still get to receive the call."

We don't need to have taken the phone across the barrier. Frisk can have left and the phone can still be in the underground.

"But if Frisk did cross the Barrier, then that's Option 1-Meaning Neutral Runs would be fine for Chara's plan, so it makes sense why they only said "another path" while not explicitly telling you to not kill a single monster."

But it then doesn't make sense why Chara doesn't destroy everything on a neutral route if they can leave at any time.
