That statement doesn't make any sense.
Dithering
is applying noise patterns to a raster image in order to prevent certain artifacts, most commonly used to prevent color banding.
Rasterization
is converting vector graphics (ie: a svg) into a raster image (a matrix of pixels). You can also dither vector graphics after rasterizing them.
The reason dithering is important in ebooks is because their images weren't optimized for the e-ink palette beforehand.
The rest of the statement sounds like a self made assertion.
