Thanks guys, TM has all the slack taking out.

The COM moves during the FbC. There is little to no movement of the COM during transfer. That is why I asked if they have this backwards. The COM moves during the shift. The transfer happens from toe touch onwards.
Your description fits with the way I was initially labeling the two movements. However, the BBD guys seems to be using "shift" and "transfer" in the opposite manner from what you described here. Since there are a number of us who post/read in both places, it makes sense to me to have some consistency between the sites.

His hips and lowerbody are late. Starts the swing with the upperbody so it seems like all the slack is taken out. Upperbody swing.
