Just to point this out: you are somewhat redundant in your post, and slightly incorrect.
The Instant death rule itself only cares about S=2*T; this is why all weapons that inflict "instant Death" also have the caveat that the Toughness of the wounded model does not matter to those weapons.
Now I had said Slightly Incorrect do to the Syntax of your statement, the actual Statement itself is more or less correct.
