Description:

In the part 'when the list is small enough to fit into a single index
"tuple" along with the key value' should the word "tuple" be replaced by the
word "page"?

If I'm not mistaken GIN will replace posting list to posting tree (and so shift it to another page) when on a current page there is not enough space. But this does not necessarily mean that page is not enough to accommodate current tuple(1). This rather means space left on a page is not necessary due to occupation by neighbouring tuples. (2)

If we just replace tuple -> page we'll get meaning (1) which is not precisely so.

I think existing description is accurate and doesn't need change basically.

Thanks for your question anyway!

Best regards,
