But what kind of hand is then double first, and then bid 4S?

Nobody gave an example

Is this one close?

AKQJx x KQ10 AKxx

That hand would do so, but so would a worse hand (even an ace lighter). Double then 4♠ shows flexibility for other strains, not a better hand than a direct 4♠.

It's hard to say pass is "100% clear" when even on the example offered by the person who thinks so slam would make with the minor suits reversed. So since we could easily have slam, or easily not have slam, maybe inviting is 100% clear...
