First, Windows 8.1 will be upgraded to Windows 10.
I'm not sure Microsoft has told us how the ISO will be distributed, but if you have no DVD, not to worry. You can use a flash drive for the ISO. Check here for instructions: USB Flash Drive - Create to Install Windows 10 - Windows 10 Forums
I wondered what was the explanation of this then?

You are dead right, Winona, but there will be many naive users who think that the little box in the notification area will be safe to use, since Microsoft says "this PC is compatible", and the upgrade will just be a click or so away.
