The solution is ambiguous. First word RMWO/3412 according to solution is 3rd letter W, 4th letter O, 1st letter R, 2nd letter M (WORM). But you could also infer: W is over 1, so W is the 1st letter. O is over 2, so O is 2nd letter, etc. Yielding (again) WORM. If you apply latter logic to word 2, you get EOHL. I submit my logic is just as valid as the stated solution, but it yields gobbledy-gook.
