Any difference between "denied Dexterity" and attacker "ignoring Dexterity"?

[johstas]

The following came up in one of our sessions:

The attacker was invisible through Greater Invisibility but was not using stealth. The party was aware of his presence via Detect Magic

The ftr of the party was hasted and was using combat expertise, thus getting a +4 dodge bonus to AC. When the attacker attacks according to RAW:

"Invisible creatures are visually undetectable. An invisible creature gains a +2 bonus on attack rolls against sighted opponents, and ignores its opponents' Dexterity bonuses to AC (if any). See the invisibility special ability."

The question is the following. Is ignoring an opponent bonus the same as the opponent being denied the bonus according to RAW? Dodge bonuses are lost only when the defender is denied his dexterity bonus. Could one argue that when the defender is attacked by an invisible but not stealthy attacker, he does not get his dex bonus to ac but still gets his dodge bonuses?

They are the same thing, just worded differently.

And one way to see that they are the same thing is that the table for "Combat Modifiers" in the Combat chapter lists "invisible" with a subtexted "2". This "2" points to "The defender loses any Dexterity bonus to AC."
