Pollen is cheap and male trees overproduce it to get an edge over other male trees. Most polen just fall to the floor, a tiny part is lucky and reach the flowers in the female trees.

That's why many plants have nice flowers and use the help of insect to transport the pollen from a plant to another plant. (By the way, the yellow balls in the legs of the bees are pollen that they collect and take to the hive, for food. They "stole" most of the pollen, a small part drops in the other flower.)

Also, the link in the article in the sentence "The pollen grains do not just get to the female trees by accident; rather they are drawn there by this mutual attraction." is not a good justification of that "fact".
