Why does farmers insurance sometimes insist on talking in person about your home owners insurance policy?

Various issues can arise which an insurance company might want to talk about. These can include, late payment of a premium, a suggestion to increase your amount of insurance, questions about a change of beneficiary, questions about a claim, etc.

Edit from asker: Turns out in this case it was basically an up-selling endeavor. They basically ask a lot of questions and then recommend increased coverage in areas.
