Textbook problem - chain structure with cis and trans

For the example on page 17 of the organic chemistry textbook, why is (E)-3,7-Dimethylocta-1,3,7-triene trans and not cis? Doesn't the atom group attached the double bonds indicate that this is a cis stricture?

For this question look at the two substituents that are coming off the respective carbon-carbon double bonds, one is pointing up while the other is pointing down, meaning the substituents are on opposite sides of the double bonds indicating trans.
