I don’t think this really addresses the substance of the question. I understand well the concept that we can imagine things which are illusions in general. I have specific mechanics level questions about how it applies to the psychological arrow of time.
The point of the stairs being a spiral is that they obey some relation to each other (like how the laws of physics are a relationship between past and future). The analogue of “time passing” is stair 15 spiraling to stair 16. But the thing is, I’m not committing to agreeing with Alice by saying that. According to Bob, the stairs are already a spiral. Stair 15 already spirals up to stair 16 just by virtue of the stairs being a spiral, which is no illusion.

Yet again , that is direction , not flow. Direction means the stairs have an order...but flow means you can only be “on” one a time, which is an additional property.
