Yes, the BITS-related issue was resolved and I am aware that every Root Certificate Update has the same KB number.
When I ran a custom scan earlier this month (Mar), it offered the 'Nov 2013 Update For Windows XP Update' so I knew that it was the 'same' update for Nov 13 and not a 'new' update for Mar 14.
I can only think that the Nov 2013 update did not install properly (which is why it was offered again) but it does not explain why it was offered 4 months later (as opposed to being offered during the next set of updates in Dec).
