I don't have any knowledge on this specific path, so I think it'd be inappropriate if I changed the accessibility tags myself. The reason I reverted is because the name change was clearly not something that would be a real name. Such as "Private Road, not Fairhaven Walk" or "Privat". I noticed this name change on osmcha while looking out for, funnily enough, some other names changes, and I thought I'd fix it as it seemed strange to me.
