Shield bearers vs killing blow?

[skyth]

I was reading through the Dwarf army book and had an interesting thought-

A Dwarf lord with shieldbearers counts as a single model with a unit strength of 3.

Killing Blow only works on a model with a unit strength of 2 or less.

This would mean that a Dwarf Lord with Shieldbearers would be immune to killing blow. Am I reading this right, or was this FAQ'd?

Correct - makes the lord immune except to those that have killing blow vs any size.

It was one of those "how can GW let such a broken rule slip by???" things before they threw the baby out with the bathwater in all the most recent army books.
