One can prove that in any case where this works, one can equivalently use the standard product rule based version of the integration by parts formula. Similar results hold for triple products and so on. (I did a proof of this on my own time back in High School after figuring out that one could produce an alternative formula to the usual integration by parts by using the quotient rule instead of the product rule).
