Once a person has been acquitted or sentenced, or the proceedings come to an end in some other way, proceedings cease to be 'active' and there is much more scope for commenting on the proceedings and the convicted person and publishing material which it was not possible to disseminate before or during the trial. In practice, once a defendant has been convicted, even if they have not been sentenced (sometimes sentencing is delayed), the media treats the proceedings as no longer 'active'. This is because sentencing in the Crown Court is carried out by professional judges who the law deems will not easily be prejudiced by media reports.
There is no sub judice now. You can say or print what you like. The young 'man' has been convicted and the case is no longer active.
