Why doesn't the allylic radical resonate in this allylic halogenation reaction?

4 methyl cyclohexene is treated with NBS and heat and the answer is 4 methyl 6 bromo cyclohexane where 2 enantiomers were given where Br is in the same position but one molecule had it on dash and one had it on wedge. my question is, why didn't the allylic radical resonate, giving another molecule with Br and pi bond at different carbon positions ?
