Not so much "imply" as "states".
By moving the input column down a cell at a time, you are effectively doing the same action as turning the code wheel to generate new letter combinations. There's 26 possible positions, and it takes about 45 seconds to look at them all - that's the point of doing it in Excel (Google Sheets/Open Office/Lotus 1-2-3/Whatever).
The two messages each have a different combination on the code wheel, so that in both messages the first six letters translate to the exact same individual phrase, which is the keycode. This would be how people would translate coded messages to send to each other - everyone in the circle knows the keycode, so you just set the code wheel to whatever you feel like, then write your message with letter substitutions, starting with the keycode. Then the receiver only has to set their code wheel so that the coded message translates the first six letters back to the keycode and the rest of the message pops out.
When you have the right keycode you can then read any mesage which starts with the keycode by setting the codewheel so the keycode is translated properly. The keycode here appears to me to be six characters in a gibberish order, but it is identical in both messages. That's why I think it's a keycode.
Just move the first column down until everything except the first six letters makes sense; one of the messages will pop right out at you. Then move the first column so that the first six letters are identical to the first six letters in the other message, and that'll pop out too.
