Jun 9, 2021 at 14:03 comment added David E Speyer I'll admit I wrote this comment without rereading the paper, on the basis of a conversation I remember with Dylan, near when the paper come out, when he drew the infinite spiral for me. Let me see if I can find it in the paper.

Jun 9, 2021 at 13:59 comment added David E Speyer Have you read Fomin-Shapiro-Thurston's second paper arxiv.org/abs/1210.5569 ? I think this spiraling construction appears there. (I don't know the answer to your question, though.)
