Spillover fire from automatic road destruction?

[offsides]

When a unit attacks the road in its own hex (automatic destruction per 13.01.3), it it supposed to generate spillover fire against other units in the hex? My reading of the rules infers no, but that's what happened yesterday - I used a GEV to cut the road in the hex it was in, which then rolled and disabled one of the other GEVs in the hex! But since it's not explicit in the rules, I can't tell if it's a bug or just a different interpretation of the rules...
