I don't think we know that it's Rika's practice video - we can't see the videographer. I'm not sure where Rika is training, but assuming that it is a public space, then anyone could take video and post it online.
The video was taken at the Broadmoor World Arena Ice Hall, on the NHL rink, in Colorado Springs....the OLY training center sign is easily visible in the video. Hasn't Rika trained there in the past on occasion? ..
