You don't have a fire lane until after the attack that created it. Declare attack and intent to place FL, roll, resolve initial attack, place FL marker. (Now the FL exists.)Well, all it says is:
7.55 MANDATORY FG: If Good Order units/weapons in the same Location are going to fire at the same target (i.e., at both the same Location and the same unit and the same "simultaneous" [8.1] MF/MP expenditure; see D3.5) during the same phase they must form a FG [EXC: Fire Lane; 9.22]; they may not attack separately except with ordnance/FT/DC or the subsequent shots of multiple ROF weapons (9.2).
So, your guess is as good as mine as to what "EXC: Fire Lane" is supposed to mean, but I can only assume it applies to firelanes in general, both their placement and resolution.
Multiple MG placing FL in the same hex-grain attack individually, not as one big fire group. That's why there's an exception for fire lanes.
