SOPP327: I recently purchased your fingering for BWV 553

This question was sent by Timothy and he wrote: “I recently purchased your fingering for BWV 553 (https://secrets-of-organ-playing.myshopify.com/products/prelude-and-fugue-in-c-major-bwv-553), and I stopped dead at the transition from the first page to the second. The last right-hand note on the first page specifies finger 3, and the first note on the second page is also 3. Is that a misprint? Am I missing something important? How can the third finger jump like that in the middle of a fast 16th note passage? Timothy
