What's the meaning of this code?

[temnix]

IF
    WeaponEffectiveVs(NearestEnemyOf(Myself),MAINHAND)
    WeaponCanDamage(NearestEnemyOf(Myself),MAINHAND)
    See(NearestEnemyOf(Myself))
    False()
THEN
    RESPONSE #100
        NoAction()
END

And -

IF
    WeaponEffectiveVs(SixthNearestEnemyOf(Myself),MAINHAND)
    WeaponCanDamage(SixthNearestEnemyOf(Myself),MAINHAND)
    !StateCheck(SixthNearestEnemyOf(Myself),STATE_PANIC)
    CheckStatLT(SixthNearestEnemyOf(Myself),1,STONESKINS)
    !StateCheck(SixthNearestEnemyOf(Myself),STATE_MIRRORIMAGE)
    See(SixthNearestEnemyOf(Myself))
    False()
THEN
    RESPONSE #100
        NoAction()
END

The triggers end with False(), these blocks will never activate. What's the point?

They are meant to set "LastSeenBy(Myself)" to the desired object. See here for further details.
