I don't understand your second point, though. 1N:2C, 2H:3N and 1N:2C, 2S:3N are equally informative to oppo.
Exactly, after 1NT-2
♣-2M-3NT-p there's the same amount of information leaked: 4M and 2-3OM, nothing known about the minors. However, when responder holds 4
♥ opener can't tell he has 4-4M before we find a fit, while with 4
♠ in responder's hand opener has to describe his full hand. Hence the difference in approach.
