Can a soft bounce still turn to hard bounce

Read from AWS blog post written in 2012 (https://aws.amazon.com/blogs/messaging-and-targeting/email-definitions-bounces): that SES will automatically try to resend a message that has generated a soft bounce over a period of time until the message either delivers or the system will no longer retry the delivery and in turn generates a hard bounce. Is this still valid? If it is, does this mean that the event/notification we received after 840 minutes is for that final hard bounce? Or it still depends on the bounceType that we received?
