The objects that you are referring to in your post, were provided to me as an MES Member of Applecore, although I understand they are chargeable for those not on support.
I have used the beam and block floor and tile object on a number of projects to help with our 2D documentation. What the video does not show you is the flexibility in each object.
I spoke to the technical team at Applecore recently and they informed me that the videos are part of a marketing exercise designed to get people talking. It seems to be working, in my AutoCAD days this would have taken me 15-20 mins to draw!
It is also worth keeping an eye on their youtube channel , this renovation movie was posted this week and cannot wait for Archicad 15
