We investigate the analytic properties of the exact magnon S matrix of string theory on AdS3 × S3 × T4 with R–R flux. We show that the previously proposed dressing factors have the exact double-pole/zero structure expected from Landau box diagrams. This constitutes a strong consistency check of our dressing factors, much as the Dorey–Hofman–Maldacena poles do for the all-loop dressing factor in AdS5 × S5.
