It has nothing to do with scatter mode, though with the highly selective cut and paste approach you took, I can see
how it might appear that way. Here is the statement back in its original context:
Unusually Fast. Unlike most operating systems, the Tiny Core can run completely from RAM. Individuals with RAM to spare can even use Tiny Core to load and run their programs from RAM (you didn't know your computer could run Open Office and Firefox so quick). Experienced users can still install Tiny Core to disk, but Tiny Core can run in 48 megabytes of RAM ... or less.
All it says is that if you have enough RAM, you can basically keep all your extensions loaded in memory, but if you have
a much more modest system, you can still run Tinycore.
