here's the rub
How is this any different that normal Stayman?
Lets assume that you open 2NT with a 3=5=3=2 hand.
Partner bids 3♣ ("normal" Stayman)
I don't know about you, but I bid 3♥
NORMAL stayman asks you to show a 4+ card major.
What distinguishes Puppet Stayman is 3M responses that specifically show 5 card majors.
That is what needs to be disclosed...
I think everyone just understands that when you explain "4 or 5 card major", that it means that the responses will distinguish the cases. Normally, mentions of suit lengths includes longer lengths (e.g. "5-card majors" allows opening a 6-card suit), so there must be a reason you specifically mentioned it.
The nice thing about talking to people, rather than automata, is that you can expect them to make inferences from the way you answer a question. It's a normal part of human use of language, so we don't have to explain everything in detail all the time.
This is also why it's adequate to explain "asks for XXX" rather than "has a hand where it would be useful to know if you have XXX". It's obvious that someone asks a question because they need to know the answer. And it's general bridge knowledge what types of hands would find the information useful (unless your partnership has special agreements about when they ask certain questions).
If the opponent needs more clarification, they can always ask further questions. But I don't think it's necessary to go into this in the initial explanation.
