Nope, this is binary compatibility. The apps you see in the screenshot are binaries straight from Windows 1 install media. Literally every 16- or 32-bit version of Windows from 1 to 8 will run Windows 1 apps. I'm sorry if I was unclear in my wording, I mean the modern Windows version must be 32-bit to be able to run 16-bit Windows apps.
