Question Regarding Coach Rules

By adeangel, in Letters from Whitechapel

Hello everyone. Reading the rules for Letters from Whitechapel I was curious about Special Movements for Jack, Coaches to be more specific. I read where you cannot backtrack to the same number (example: 149 > 138 > 149. I understand you cannot go back to the same number but was curious if you can backtrack to a different number. Would it be a legal move if I went from 149 > 164 > 136? I can understand this would be very confusing for the Police and well...that pretty much is the point to my question. Thanks everyone :)
