For “EVERY clue” “the two answers are entered in ways suggesting their sets typeS, one in EACH WAY.”
Seems pretty unambiguous.
It would be very clever if spinning the letters in other types (for instance turning the page upside down to write in the up answers) would allow two distinct forms of entry in set three but after a couple of days of playing with it I cannot see it.
I am going to submit as I have it but I sense a trap.
