The reference point could be any point, but the purpose is for example if you copy a drawing of a wheel it makes sense to choose the hub/axis as reference point, so when you reinsert it you can place it properly.

The other query: I can not confirm/reproduce this behaviour. Maybe the layer of not copied entities is locked?
