Ordering Clickteam Fusion 2.5 Dev and Android export

In the near future I plan on buying Clickteam Fusion 2.5 Dev and the Android export. I would like to know what a Download + Shipped is. My Idea is that you can download the product and you get an installation disk in-case your computer fries or something. Am I correct?

Yes that is correct.

You can also register your serial numbers here on the forums and get the installers from the Community Passport.
Saving the installers to a CD-ROM is also a good option for having easy access to it later.
