PVS-Studio warning V564 for UnrealEngine4

bool VertInfluencedByActiveBone(
       FParticleEmitterInstance* Owner,
       USkeletalMeshComponent* InSkelMeshComponent,
       int32 InVertexIndex,
       int32* OutBoneIndex = NULL);

void UParticleModuleLocationSkelVertSurface::Spawn(....)
{
  ....
  int32 BoneIndex1, BoneIndex2, BoneIndex3;
  BoneIndex1 = BoneIndex2 = BoneIndex3 = INDEX_NONE;

  if(!VertInfluencedByActiveBone(
        Owner, SourceComponent, VertIndex[0], &BoneIndex1) &&
     !VertInfluencedByActiveBone(
        Owner, SourceComponent, VertIndex[1], &BoneIndex2) &&
     !VertInfluencedByActiveBone(
        Owner, SourceComponent, VertIndex[2]) &BoneIndex3)
  {
  ....
}

Beautiful Bug! This is what should have been written here: !VertInfluencedByActiveBone(Owner, SourceComponent, VertIndex[2], &BoneIndex3))
