I'll post some of the answers that Riza provided.

"From how I see it, both translations[official and unofficial] are very vague and didn't even acknowledge that Bill said 'the same nen ability'"

"If I were reading that I'd figure he's still talking specifically about conjuration in regards to the beasts"

"And that you can either conjure things with the risk of everyone seeing it, or conjure things that only Nen users can see"

"So two different ways of conjuring, and hiding your conjuration without the use of In"

"So first Kurapika was explaining how Nen users can see the beast but normal people can't, and how everyone could see the snakes. Since Conjuration = everyone can see it unless In is used, Bill is asked if the conjuration of the snakes and the ability used for the beasts are different abilities, to which Bill says they're the same in the big knot (meaning there's much more to the usual Conjuration). Which you figure he means that the beasts are conjured, just in a different way than the traditional conjuration."

"He gives an example using the snakes, and Kurapika hops in to give and example using the current situation about the beasts. So there is no explicit statement saying that 'Yes, the guardian beasts are conjured,' but with everything taken to account that's what you'd figure."

"And after Kurapika gives his example, he realizes that the different risk to planting parasites in so many people might be that if one person is able to withdraw, the beasts will all disappear. So I'd say the beasts are conjured and that once the vow is broken, the ability will too"

After reading her explanation and reading and rereading the versions, I see how the logic of the explanation makes sense although Kurapika's conclusion seems to be a very large logical leap (but this is Togashi's fault).

If only Nen users can see the GSBs and normal people can't (the strangest thing), it could be related to the indirect war that is going on between the princes and normal people seeing the beasts could somehow disrupt the intended Succession War.
