Running through to Wigan would give the stations beyond Headbolt Lane a better service and better connections at Wigan, and allow Northern to truncate the existing Kirkby service at Wallgate.
It also makes more sense to run through to a major population centre than to terminate in the arse end of nowhere for political reasons.
It also enables the simplification of the Wigan-Manchester pattern post-electrification, to 2x EMU to North Western via Bolton and 2x DMU to Southport via Atherton, with no need to run the Kirkby in one of those paths.
