In summary of the original question, if the Captain in question feels the need to include this in the brief good on him! Personally, I wouldn't. Be thankful that you fly with someone who is a thinker and has probably thought this scenario through. Believe me some haven't and would die procedurally.
Safe flying.
ps. type runway incursion into YouTube, scary stuff.
