Purchase of Adobe All Creative Apps when I already have some of them

Hello.  I have been using some Adobe products  like Acrobat Pro and InDesign for years.  Recently I purchased a yearly subscription, payed monthly for Adobe After Effects and Adobe Premiere Pro.  Today, I just noticed that I can purchase a yearly subscription with monthly payments for twenty Apps at once, which includes that ones that I already have.  That would defintely be the preferred way to go since I am already paying more for only those four Apps than I would be paying for All Apps.  

My question is, if I purchase All Apps for $52.99 per month as a yearly subscription, payed monthly, what happens to the four Apps subscriptions that I alreay have?  I do not want to pay separately for them if I am receiving them in the All Apps package deal.  Please let me know.
