It's written in the judgement, section 84:
"Apple itself must (having created the confusion) make the position clear: that it acknowledges that the court has decided that these Samsung products do not infringe its registered design. The acknowledgement must come from the horse's mouth. Nothing short of that will be sure to do the job completely."
The judge took believed Apple deserved it because they had to lean up the mess they created. The judgement (http://www.bailii.org/ew/cases/EWCA/Civ/2012/1339.html) is very easy to read and the summary of the Publicity Appeal (section 64 onwards) goes through this verdict. I was quite surprised at how informal and layman-oriented the language was.
