Thanks Bekol,
I appreciate the info. It makes sense and I agree with you, but unfortunately as you said there are a lot of places that say "it's just a label".
It is just a label if the transfer of frequency happens whenever the handing off sector feels like transferring it, or in a regimented way at the defined sector boundary. It is a whole lot more than just a label if it is the silent agreement between two controllers that one is happy to give you the aircraft and the other is happy to recieve it.
It works like clockwork when everyone knows what to do and how, and I do think it is the safest way of handling things but I am yet to convince many here.
