Bobby, it's not as complicated as it first appears. I might make a hash of this...
There are three clues A, B and C.
There are three given answer lengths 1,2 and 3.
There are three entries X, Y and Z.
Clue A could have answer length 1 and go at position X(or Y or Z)
Clue A could have answer length 2 and go at position X(or Y or Z)
Clue A could have answer length 3 and go at position X(or Y or Z).
Clue B...the same reasoning.
It's basically to make it harder for the solver I think - work out what constitutes the clue and then answer it without knowing the exact length.
