Indeed, this link only makes sense if Gatwick gets its second runway.
Equally, it would greatly strengthen the business case for that second
runway. It's not allowed until after 2019,

Nitpick: Gatwick has got two runways already. The agreement is to only
use one at a time.

Agreement or no agreement, the two runways are too close together
(about 200 metres) to allow safe operation of both of them as runways
at the same time.

The proposal for a second runway is a little over 1km to the south of
the existing one, with the new (third) terminal between the runways.
