Orgo-Predicting Product question

I don't understand how there was a abstraction of hydrogen from a vinyl location. I do get how the first product is formed. Not the second one.

Reading text and from my knowledge of chemistry, this is a bona fide error in the book.

It is an allylic abstraction not an allylic abstraction.  There is no vinyl abstraction taking place.

This almost certainly done at increased temperatures.  The homolytic cleavage of the allylic bond forms a resonance stablilized radical forming the mixture of products.

God, Im an idiot.

I see it now.  Yes that answer is wrong as drawn.  But the chemistry is sound.

They would be different with respect to the labeled C13, however.

I apologize.
