After doing some research, the satellite at 72.5 W is the DirecTV 1R which can only do 16 TPs, just the even ones so if Dish wants to use that slot sooner than they need to provide a DBS satellite.
This is really interesting because they only added the odd tps to the tables and they go all the way to TP31. They're probably moving one of their own spare satellites soon?
