looks like its splitting, I believe they deflate and they actually inflate little bubbles when they split, I had one do that before at the aquarium shop I worked at a long time ago.
This one split once before and when it did, it just split. No bubbles like this or anything close to it. I found another thread with a RBTA that was "budding" and it too looked completely different although that one was sprouted a new anemone off the stem. Time will tell I guess. It's happy, healthy and doing well so that is all that counts.
