Not at all. Article 6 says in case of delays passing the necessary duration, passengers become entitled to care, and later to abandonment. Article 7 defines the compensation entitlements for denied boarding and cancellation as referred to in articles 4 and 5. The only connection in the legislation as made between articles 6 and 7 is that they are consecutive.
There was no ambiguity. Delay compensation was never envisaged. It was created out of whole cloth by the ECJ.
