Yep, those are male flowers in with the female flowers.
Seeds are in the female cones. You usually don't have seeds in whole cone hops. I have seen a lot in British, some in US, and was astonished when I saw some floating in the boil using German hops. The Germans feel that they do not want seeds as that is a sign of low quality hops.
Edit, the seeds in the hop cone are the result of pollination with a male hop. You usually don't know what the male was, so if you plant the seeds the result will be odds less that shooting craps that something good results. That is why we get rhizomes to plant.
