Wonderfully logical ... but from racing I know cooling logic, like military plans, never survives contact with the enemy! 🙂
I seem to remember a past thread where someone had done real-world 'wool tuft' airflow pics out on the road and air was going in and not going in surprisingly strangely.
Fortunately my car doesn't suffer from overheating (touch wood) but if it did I'd have a few mods I'd try after seeing that.
