Extreme Sudoku: Simon Gets Duped!

Today's brilliant puzzle is by tenaliraman and was recommended by one of our testers as a great puzzle for learning about the "Between Line" constraint. What the So-and-So didn't reveal is that this puzzle is rated 5/5 for difficulty and also uses Disjoint Sets...!!! You can play it here:

Rules:
Normal sudoku rules apply. Cells in the same relative position with respect to a box cannot contain identical digits. (So eg, r1c1 and r4c4 cannot contain the same digit). Clues outside the grid give the sum of the digits along the indicated diagonal. Digits along such a diagonal may repeat if allowed by other rules. The digits along lines in the grid must be BETWEEN the two digits in that line’s circles (eg if the circles contained 2&7 then the digits on the line could only be from 3/4/5/6). Digits on the lines may repeat if allowed by other rules.
