ODF style:page-usage="mirrored" and Word's w:mirrorMargins make the declared left/right the inner/outer pair, which an even page swaps. Read, rendered and written back in both formats; the body rides the per-block inset a section's own margins already use, the header and footer band moves with it. Measured on a mirrored two-column file: its page 2 went from 12.7-184.1mm to 31.8-203.2, which is LibreOffice's to 0.1mm, and its running head with it.
