Expiration Date Clarification. 730 days OR 90 days after serving size is complete?

Hi! The Expiration dates on FBA products is a bit confusing. The section Shelf-life requirements for expiration-dated products starts with saying;

"At the time of check-in at Amazon fulfillment center, all products must have a remaining shelf life that allows sufficient time for the product to be consumed in full, plus an additional 90 days. For example, a bottle of supplements with 240 daily servings must have a remaining shelf life of 240 days and an additional 90 days, which makes 330 days."

Then the chart below shows all supplements must meet the requirement of 730 days.

This appears to be contradictory information.

Can you please clarify.
