I am sure I read this in a NATS DOC !
This would in effect make it parallel approaches straight in from somewhere just south of Southend.
It would help if you could remember where you saw that.
The only document from NATS that I've seen discussing airspace usage with a third LHR runway (prepared by them for the Airports Commission) is this one, which says the precise opposite:

It suggests that arrival routings would use an S-shaped "trombone" concept (not all that dissimilar to current practice) and that holds would still be required to cater for situations where short-term demand exceeds runway capacity.
