I promise I'm not arguing. Are we sure this isn't from someone repainting this as a Yeti? I was a big fan back in the day of both companies, if this was from '89, they had been welding steel since '85 at that point and were welding 'FRO's as steel through '91-ish. It doesn't make since that they would do this. However, there were a bunch of riders they had that started at Mongoose, maybe they painted one because they hadn't prepped a frame something for a new rider? I don't know, that is certainly a curiosity frame. Yeti admitted to copying the loop-tail that Mongoose had on their BMX bikes, and then Mongoose then got influenced by Yeti to do the same style on their aluminum mountain bikes.
Also Easton wasn't involved until '92, why would there be an '89 frame that was used for 3 years later? A '92 Mongoose IBOC frame looks nothing like that either.
