Rookie and legacy status are very gray areas in the early days of FIRST. Technically, 131 would be a legacy team if they had not taken 1993 off. The rookie status rules that you see today weren't started until a few years ago.
The closest ruling I have ever received as to what considered a team consistent in the old days is that team status flowed through the main mentor registering the team. As long as that was consistent, the team was consistent. This is the grey where 148 and 190 are still considered legacy even though they both changed schools.
Sidenote: In my years I've found it's just not worth it to argue with Mr Grady about team history in the early to mid 90s. I pick my battles, and I recommend you do the same
