LO org says that LO portable can function without a launcher

[LibreOffice web site](https://www.libreoffice.org/download/portable-versions/) says about LibreOffice portable, that can run without the PortableApps platform.

> LibreOffice Portable ... It is packaged in PortableApps.com format so it can work with the PortableApps.com platform
> and its automatic updater and app store, **work with other portable menus, or work by itself from a USB**, cloud or local drive.

I thought that the portable apps launcher, is a need because aplications write some keys to windows registry and retrieve files from the user directory (X:\users\\AppData\Roaming\LibreOffice\), and using it from any storage device whose drive letter can change in every other moment, is a potential problem.

I ask, It is true? Is the Document Foundation, misleading its users to believe that the LibreOffice portable can be launch without a portable launcher? And specifically, with portableapps.com launcher?
