The 'bypass' style series push/pull connects the two pickups together in series, that is bridge -> neck -> out, whenever the push/pull is 'up' regardless of the 3-way's position. When 'down' you get the standard bridge, bridge + neck (parallel), neck on the 3-way.

If you're talking about wanting to switch each pickup's coils between series (the standard humbucker setting) and parallel then that is something else entirely, and a different configuration to the one you originally posted.
