Just had a look at my update history. This one started on 06/09/12 - it showed days of 'failed', then 'successful'. the next day (and every day for a week), the same update showed as 'failed', then eventually 'successful'.
Just noticed that the definition number in brackets are different, so it's MSE updating definitions but under the same KB number. What I don't understand, though, is why so many of them are failing to install.
