I don't really think that there was an issue with how "Trials and Tribble-ations" glossed over the difference. "We do not disucss it with outsiders."
It was ENT that decided that the reason had to be shown.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
