The more I see the Vettel incident, the more I think he should have been DQ'd - although I don't actually think he meant to ram him - he put himself alongside Hamilton and clearly turned into him (accidently or deliberately). Do that in any other race or situation and it's an immediate black flag.

Regarding the stewards investigating after the race - the commentators on my feed certainly believed that the incident was broken into 2 incidents;
- the rear shunting, to be investigated after the race
- the side-swipe that was penalised during the race

But yeah - it wasn't clear at all. I'm pretty certain that I saw a stewards message about the investigation happening after the race.
