I asked a friend, he says they can be using Adobe After Effects (his preference) or Final Cut Pro. I was surprised, but apparently these tools are fit to do this kind of animation. The narrative can be a more difficult part, unless the video involves much custom graphics (this one appears to do a decent job reusing a few primitives). By narrative I mean not just the voice, which I was told is often done by outsourcing to studios out there, but the script in general. Just my 2 cents, maybe someone can give more info.
