If you could PM me these articles I'd love to see them because I have not been able to find any evidence based research to suggest that either direction is preferable. The trainers/vets I worked for all said it did not matter - the goal is to keep the tendons in the natural/neutral position with even tension. Maybe it's because I wrap racehorses, but 99% of horses at the track are wrapped that way. To each there own. If I was given conclusive evidence that either direction was better, I would most certainly change my ways and present it to the trainers/vets whom I work for - these are the folks who taught me. No, I have not hurt a horse yet, but helped many.
To the OP, sorry for the hijack.
