Yes, it was a bluff to scare Ghani, the obstruction to peace talks, into stepping away, but after all the assurances Pelosi and Biden gave Ghani that they’d have his back after the election, this bluff no longer had teeth. Biden knew he fucked up but still wanted out so decided to hide behind the bluff while letting the ANDSF and the Taliban have a war, funding it at $4 billion a year for 4 years. The ANDSF was foolishly expected to come out on top.
