Of course it did, it was pretty normal around the time of the Mrs Johnson, Mia and Diane updates and up until the Roxxy update.
If you call the three-frames animations of the Erik/Mrs. Johnson content comparable to what is provided now... And Mia/Helen contained three scenes (with one anal/vaginal modification) -- so if that is comparable, too... The Diane update was imo one of the weakest of the modern updates, it also only provided one real scene with two angles -- and it took four months, not two and a half.
So I suggest you adjust your filter to what you find comparable.
Here is for your reference what was delivered in what time frame in the past:

Even the Roxxy update (still one of the best I ever saw in any game imo) took over three months, not two and a half.
