In Lk 8:5, the word 'seed' in Greek was masculine, so why were its pronouns neuter?

Lk 8:

5 “A sower went out to sow his seed [masculine]. And as he sowed, some [neuter] fell along the path and was trampled underfoot, and the birds of the air devoured it [neuter]."

Koine Greek collective (masculine, neuter, or feminine) nouns were sometimes referred to by neuter pronouns regardless of the antecedent's gender because the neuter gender in Greek could function as a generic or collective reference, focusing on the group rather than its individual members.
