Question about Epson EcoTank ET-8500

Epson's warranty extension campaign extends the warranty to 3 years. However, if I choose the Digitecoption extension to 5 years, it assumes a 2-year standard warranty. So if I understand correctly, it would be one year double warranty (1x Digitecoption and once Epson action). Or does the warranty then extend to 6 years? Thanks for the answer!
