How can a descent radial be defined from a VOR other than the VOR at the aerodrome?

@EXDAC thank you, could you give more examples, i am specific about one approach at VOBG India, the aerodrome has a vor BIA which is located inside and the Descent radial given is from another VOR BBG which is located 10nm outside the airport, i haven't seen anything like this. Usually, descent radials are given from the VOR located at the aerodrome where you shoot an approach.

is this common?
