You didn't note your ruleset; assuming ASA, partner needs to update his rules knowledge.

Also, you are being overly limiting in your interpretation. There were several changes associated with the double base this year, with the net affect being: Plays on the batter-runner first time past the bag have restrictions on who must play which bag, but once the BR has passed 1B the first time, there is one big base available to both offense and defense. Not just on pickoff plays; on any play thereafter.

This explanation and verbiage from the mouth of Craig Cress, ASA National Director of Umpires.
