This pattern — where someone vandalises a label of a given name item, thus making many entries for people with that name appear incorrect — is quite common. I frequently revert multiple such cases per day. My suspicion is that it's usually done by someone thinking that they're only changing a single entry, and not realising just how disruptive it's likely to be (in the case above,*everyone* called John!)
In some ways the extremely large scope is useful, in that it's more likely that someone will spot the problem quickly, but it's definitely not uncommon for such a change to remain live for 12 hours or more, and sometimes multiple days, before someone reverts it.

My apologies. I was looking at the wrong Q-number for revision. The pertinent Q-number to check here was https://www.wikidata.org/w/index.php?title=Q4925477&action=history (The name "John"). My mistake.

No. All edits are visible in the page history, including rollback, revert, restore, undo, etc. The only kind of edit that is not recorded is a "null edit"
- an edit that changes nothing compared to the previous version (so it's
not actually an edit). This is sometimes used to rebuild cached derived data.
- Is there some other place we could look that records such rollbacks?
No. The page history is authoritative. It reflects all changes to the page content. If you could find a way to trigger this kind of behavior, that would be a HUGE bug. Let us know.
Note that for wikitext content, this doesn't mean that it contains all changes to the visible rendering: when a transcluded template is changed, this changes the rendering, but is not visible in the page's history (but it is instead visible in the template's history). However, no transclusion mechanism exists for Wikidata entities.
