Oh, I've no doubt it's a mistake.
The problem is what do you do as a TO when a player argues 'but I never would have moved there if the enemy could have fired at me, I was just playing by the rules as written which says they cannot'.
Technically, such a player (while simultaneously being a massive toolbox) would not be wrong, as things stand.
And that's...annoying.
Issue a preemptive ruling, at TBD beginning of the tournament, before any maneuver dials have been set. Put the rulling in writing, with the explanation that you think FF made a mistake, and why you think so.
Don't wait for it to be an issue.
