I have already encountered 3 cases:
- as Warin says: create something in josm, save it as faile, send to 
osm, don't save after send, close and reopen the file, send to osm
- imports (cadastre) done (in France in a "legal" way, in Switzerland, 
Fribourg done with in an undocumented/incompatible source, repetitive 
issue with the same guy again)
- rare problems during a network outage while sending.

The only thing that remains incomprehensible is when this happens iD 
several days apart
example with the first one on your list: 
https://www.openstreetmap.org/way/1122282039 sent with iD 3 months ago. 
duplicate of a building sent 5 years ago with josm 
https://www.openstreetmap.org/way/553715102
the HOT validator didn't see anything, neither did the task validators, 
but that's another problem.

I'm willing to look at some examples of the quadruple list but in this 
format, it will be difficult to work on it with several people as it is 
impossible to mark elements as processed
