Before that change the first header paragraphs tabulator settings were not saved, after it they are. Manually adding the tabulator positions to the old doc export in Word creates the same layout with the image outflowing.

Since there are two tab positions at 8.5 cm and 17 cm but four tab characters, these are now positioned correctly. But unlike in docx, in doc these excessive tabs can not break to multiple lines, which makes the image in the docx appear and in doc disappear.

When saving the original docx to doc in Word 13 it adds an extra line break after the first tab character and deletes the last two (this is cheating...) so that it retains more or less the image position, although more to the center than right of the header.

So this is how it looked in the commit before the solution to bug #92335
This is saved with commit e84428b92a32fcd6d157291173087b3a4e2c7f35 in the bibisect-win32-6.3 repo.

Bug #92335 caused bug #128499 in the doc export and then the solution of #92335 was limited to docx. 
Now after bug #128499 is solved we have the same behavior of doc export as before bug #92335

Things have changed.
Now the DOCX initially imports in a way that sounds very similar to Word as described in comment 3. A line-break is introduced after two tabs, and the image is more or less in the center of the page.

That happened in LO 7.3 with commit 054b554b18d89b7efa87f79b5f33865252e9e789

    DOCX import: handle a subset of <w:ptab w:alignment="left">

The round-trip to DOC looks the same as DOCX in MSO and LO.

Ultimately, this is a DOCX import issue. We do not yet handle the right alignment aspect of w:ptab.
