Opp. Fire

[plloyd1010]

Issue: Do the modifiers for AT opfire and AT fire for previous action segment movement combine?
My position: No. Opfire occurs in the current action segment, thus previous action segment not relevant to this fire.
My adversary's position: They do. (I have trouble articulating his position.)

History of the modifiers has been referred to. This is how they were presented.
2nd edition:
    -1 if the target moved in the current or preceding action segment.
3rd edition:
    –1 target moved in preceding action segment
    –1 opportunity fire (13.0)
4th edition:
    —1 Target moved in the immediately preceding action segment
    —I Opportunity Fire (13.0)
    
From the replies (and counting mine or my adversary's positions), 4 people say they they don't combine, 1 person says they do. Also, one person off record says they do not combine.

The general consensus appears that the modifiers do not combine. The primary reason being the understanding that opfire fire occurs in the current action segment, thus different from previous action segment. (I sticking to rules as written question and leaving rational out.)
