Lexical sorting (string sorting/alphabetical order sorting) is what I believe they were referring to when talking about file names.

The fact that you don't have to do any parsing of the string at all, just do a straight character-by-character alphabetical sort, and they will be sorted by date, is a great benifit of this date scheme. That means in situations where no special parsing is set up (eg, in a File Explorer windows showing a folders contents sorted alphabetically) or where your string isn't strictly date only (eg, a file name format such as '2025-05-02 - Project 3.pdf') you can still have everything sorted by date just by sorting alphabetically.

Its this benifit that is lost when rolling over to 5-digit years.
