I assumed that was the intention but I'm not quite sure what purpose it serves. Being able to see the whole chain, particularly if it's very long, would be an easy way to read it.
It may sometimes end up convoluted where there are multiple replies but it's still easier than clicking on each comment to get to the next in the chain.
If you want to see the specific comment it's reply to then there is the option of clicking in reply to.
The arbitrary bit seems to be what comes up when you click on a comment number. For instance clicking on the second comment in a three comment thread gives you all 3 comments as expected https://www.lfgss.com/comments/13057398/
Clicking on the third comment only gives you the 2nd and 3rd comment https://www.lfgss.com/comments/13057404/
