Hence unless SE states outright that theory as correct ("Amdapor statues were based directly on sineaters"), I'm going to regard it as just another model reuse with no deeper lore connection or implication.
I find it a little odd that they chose to specifically draw attention to the matter in-game because if you bring Alphinaud to Mt. Gulg, he remarks that the first boss has an uncanny resemblance to the golems of Amdapor.

Granted, that's literally the only time it's brought up, so it could just be more window dressing.
