I am doing some digging into inverted kaplan, where after partner opens, 1h-1s shows 0-4 spades and a limited 1NT, and 1h-1NT shows 5+ spades, both sequences forcing.

What happens after 1h-1NT, showing 5+ spades ? I presume some rebids are natural, but say you had a balanced hand such as 2-5-3-3, does it function like forcing 1NT where 3m is 3+. Partner could have 5-2-3-3 or 5-1-4-3 and hear 2x of a minor (3+). Seems like 1h-1NT takes away playing in 1NT and creates awkward rebids, am I missing something?
