This could make total sense, I always thought they spend to much energy on what was a gimmick at this point. But maybe they were just preparing a live memoji feature until it was flawless.
You might notice that unlike Meta, Apple current approach focus solely on head avatar. But they make a point for them to be very expressive.
This also perfectly fit the privacy narrative. Expressing yourself thought an expressive live animated avatar help preserve privacy as a remote worker. My life companion colleagues never agreed to turn on their webcam, maybe they would feel more at ease with an avatar.
PS: Maybe a better video (example) of the footage used in last year daily WWDC recap. The setup for the daily recap was a memoji of Serenity Caldwell reporting thought online meeting with other developers using memoji.

Fun to see the evolution also...
It should rather be compared to other VR avatar concepts. Meta full body avatar for instance. The tech is clearly not ready and feel clumsy and add absolutely nothing. Meanwhile a floating head of some sort that can surimpose over the media you are collaborating on could be a better experience.
