That's just interpreted as "not guilty". I still don't understand why it is so hard for people to understand this.
The jury are just asked "are they guilty?" and if they don't give an answer it is, by simple virtue, not a guilty verdict. Voila, verdict of "not guilty."
UK law has precedence for defendants who did do the deed being given a not guilty verdict by the jury already. We even gave it the name "perverse verdict." The wiki page on jury nullification has details.
