The following is just my opinion:-
No no no no no!

It will never " feel like you’re pulling a 45# when it’s 65#"

However, it may feel like you are pulling 65# when you are pulling 45#tho'

Someone at sometime put forward this idea that it is somehow "like a compound" whereas it is the opposite!
When the second bow starts working the draw weight will increase not let off.
In the interests of fairness, I've never made one (nor do I plan to) and I dare say when made and set up by a skillful bowyer it will doubtless work just fine.
But it is never going to give any sort of let off as far as I can see.
I'm willing to be shown to be wrong if someone can show a force draw curve and explanation of how it is working.

Some may think they are an abomination... I couldn't possibly comment
