The idea is fairly old -- Xerox used to have a scanner like that, where the scanning area went all the way out to the edge of the scanner, and allowed books to 'hang' off the edge, while the inside page was scanned.
The bonus is that gutter effects disappear, and pages scan flat, even when the book is very stiffly bound. That is a considerable advantage.
The disadvantage is that you will be doing twice as many scanning moments, and as each of them carry a risk for folding a page, that risk increases. Scanning time increases also, but that may perhaps be offset by better OCR results, and less correction work later.
And of course there are always books where the binding is slipping or deteriorating: they won't stand even this much handling.
