No, "Mirror, Mirror" is the episode where a transporter accident makes the landing party trade places with their counter-parts from a savage alternate universe (afterwards referred to as the 'mirror universe,' a place visited in one episode of TOS, two of Enterprise, and five of DS9).

The episode with the Khoms and Yangs was "The Omega Glory," and the episodes with the grups was "Miri," after the name of the young lady in it.

Really? Because it was the '60s, and she was a black woman, and the writers never thought about the fact that she ranked Chekov and Sulu.

In-story? Because she was a staff officer, not a line officer, which is a significant difference in Naval service.
