MS Research has free reign to basically do whatever they like and it looks like they hosted the video on YouTube. So that's where the flash comes in. But that choice itself is kind of interesting because it's the exact people they want to compete with using this technology: YouTube -> Google
Most likely it wasn't give too much thought though, thankfully. Marketing is pretty hands off when it comes to MS R&D.
