Thank you very much Gilles for the insights.

It's not really your fault because it's how our brain works. If we want to get things working we are concentrating to get them working - not how to break them. It's amazing that the code worked like "intended" - that means you are a very good dev. Logical fallacies hit us every day - we are human.
