Thats correct.
As mentioned earlier in this thread older miflex hoses i have here are fine, also a new old stock (from 2017) inflator-hose i got is fine.
I know ideally you soak/clean your regs pressurized. But there are places out there where this is not possible, at least not at a reasonable effort.
So you place them unpressurized into the soak basin. Normally, as long as you don't push the purge button on the second stages, this is absolutly no problem. With my acd sealed first stage i could even place the whole set into the basin (But i don't trust it that much).
Guess what happens when the inflatorhose isn't sealing?
A solution could be to be more carefull with the hose, while soaking, because i now know that it leaks.
But i rather just have a hose on there thats up to spec.
