Here you have an example, one taken with iPhone X at its minimum focusing distance and the other with the 13 Pro matching the framing. How is the photo of the 13 Pro better? Is it sharper? Does it have more detail? Does it have any kind of depth?
Now, I 100% agree that the 13 Pro can get the sharpest macro photos; those that it was advertised for. They're absolutely incredible. For me, the 13 cameras are excellent, I couldn't be more happier with them. However, the topic of discussion here is a very specific "issue", the one that is described in the original question. And for that application, you will not get the same results even if you buy a Pro model. That's it. What's wrong with that?

Which circumstances? The ones that people are reporting here as an "issue". If you're going to recommend the Pro as an alternative solution, you should point out that for this specific application that is being discussed, the result will not be the same; although it is a lot better for other applications.
