Jump stitches lead to wrong X and Y values in .DST file

The .txt files are .dst files because Github does not want to upload .dst files.

First I tried without jumpstitch. See the file ... with line iso of jumpstitch.
All of +X, -X, +Y and -Y are correct: 500. Although -Y happens to be correct but it is taken from the +Y value, see previous issue

Now I replaced the first line by a jumpstitch. The +X and -X values are correct as sum, but they should be still 500 each. The +Y value is now 1000 rather than 500. -Y is also 1000, but that will be because of the other issue, where I reported that -Y is taken from +Y, so after that would be corrected I expect that -Y would say 0.
It looks that the counting starts from the point where the first real stitch is made.

I would expect in this case all values still to be 500. And Inkstitch agrees with that vision. I uploaded the .dst in Inkstitch and exported it as .dst and then all values are 500.
