Split before occurence number fails

GSplit

I want to split a long text file, by starting a new file whenever \id occurs in the text.
I set this up in Type and size like this.

And I get this result.

It works fine to split after the occurrence number, except then the
\id is at the end of each file, rather than the beginning.

Interesting error, we’ll try to check for the next major rewrite of the software.
