Yes, this is the correct link/form the devs I know have been using in the past.
Obviously it is a case by case basis but for the folks I know their apps were not anywhere close to a top 100 position, and the review team did for them the "right" thing and got their updates approved ASAP.
Their apps was not a first version but they had done multiple releases, and never had to ask for the expedite review. So I think that the review team took that in consideration, and on top of that the fix was required because one of the web service outside their control changed their API without notice.
(and could have used it at least once before! :-\ )
