Not sure what you're asking, but the downgrade button just stops future subscriptions from automating. The 6 dollars you payed last time will still give you a whole month, but you won't have to pay 6 dollars again next month.

"What happens when I downgrade?
You will no longer be automatically billed. Your access to Dotabuff Plus features will remain in effect until your current subscription period expires."
