Must the outside clue belong to the same puzzle as the first cell in its direction?
Generally, no. But if a number belongs to the Anglers part, the line starting in that number must enter the grid in the first cell, which must belong to the Anglers part then.
If it weren't too late (the instruction booklets are already being printed), I would change the example by moving the 2 in the second column from the top to the bottom.
