The last bit about p going low with introspection isn’t necessary. The conclusion (two-boxing preferred, or at best indifference between one-boxing and two-boxing if one is certain one will two-box) follows under CDT with the usual counterfactuals for any value of p.
The reasoning is “well, if the world is such that I am going to two-box, then I should two-box, and if the world is such that I am going to one-box, then I should two-box” Optional extension: “hmm, sounds like I’ll be two-boxing then, alas! No million dollars for me...” (Unless I wind up changing my mind or the like, which keeps p above 0).
