Quick Definition: A state the PUA reaches whereby he truly no longer cares about what other people think of him.
“No Fear. No distractions. The ability to let that which does not matter, truly slide” – Tyler Durden (Fight Club)
Every Master PUA reaches a long term indifference threshold, and also a short term one every day when he goes out when he stops caring what other people think of him in order to reach his goals. Every night there is a “Threshold” that resets, and in the long term, there is a “shamless” factor that goes into cold approach pick up. Your ego no longer stops you from achieving what you really want.

If I get this correctly (and yeah I know these terms are only signposts), it is a state of desensitization which happens when our mind learns that it is ok to express yourself freely at that time and place and it is safe to do so. there are no potential negative consequences.
I think the main difference is that indifference threshold is where you no longer care of the opinions of others and their standards which you think they impose on you, and so you no longer require their approval, and only answer to yourself. IOW, you remain your happy amused self, even if their reaction is good or bad.
External validation is where your state, and happiness is all dependent on the reaction of others, if they approve –> you keep your state/happiness. If they disapprove –>your state goes.
