I remember seeing that video of apple employees doing yoga in the apple fitness research area where they developed the watch.
However, heart rate is apparently a bad way to measure yoga exertion. Similarly, heart rate is a bad way to measure weight lifting exertion. Your heart rate just doesn't get as high and stay high like running, and so it underestimates calories by a lot.
So if they used yoga to develop the activity algorithms, then how does it perform?
(An example: 1.5 hours of power/ashtanga yoga is supposed to be about 350 calories, but a heart rate monitor will only record a hundred or so, as if you're resting or taking a light walk. I don't know how many calories weights are supposed to give you, but I've read that HR monitors are terrible for it.)
