I keep seeing Pop recommended so hijacking for an issue I ran into switching away from it - I had to completely wipe the drive prior to formatting the drive for whatever Debian based distro I was checking out.
Long story short, it was due to the bootloader for Pop remaining and interfering with the install process. So a full wipe wouldn’t be necessary most likely, just clearing your boot partition should be enough.
Maybe they mean they will dual boot between windows and a hypervisor? I’ve never considered if that’s a possibility.
