Yes it does. If on his first appearance in the Crown Court he had pleaded guilty he would have received a third off. Since this date the amount of credit he gets for pleading guilty reduces over time. A plea on the day of trial ordinarily attracts credit of 10%.
I suspect his defence will try to say to the Jury that he is a man who has accepted the things he has done wrong. On face value it's a pretty weak strategy as the Jury will hear that he has pleaded guilty to two sexual offences against the same girl.
