Bites <name> on leg emote is still triggering a rescue?

[byzanthia]

Just noticed this in a group:

< 1264h/1264H 180v/180V P: std >
< |cs +|ds +|bs +|ra +|sb +|sod +|cc +|wu +|nop +|ub +|ut +|hd +|dsd +|iw +|vip +| >     

Lizus bites Lamizapple on the leg.
[ Rescue: Lamizapple ]

< 1264h/1264H 180v/180V P: std >

I thought the "visible fighting" trigger was supposed to skip rescues for that? I see it contains this:

if string.find(matches[1], "on the leg") then
--  display("X")
  return
end

But it looks like it still tried to rescue when someone used the "bite" social command?
