this logic is completely flawed. humans are not robots working on a list of problems to solve. As you learned from your experiment there is a inconsistency and now you can work to fix it. This is how osm works and it is great that you help to make it better. the more redundancy the more automated checks can be done to find errors. BUT … see below

no, that's again wrong logic.  there is a lot of gray between black and withe. 
Humans will just stop being interested if you flood them with stupid cumbersome work. It's all about motivation and it's not possible to motivate by offering senseless challenges without any reward.
