Raster images have an intrinsic size, the number of pixels. When
scaling SVG, you scale based on the explicit size the document states.
So 50% is half of the explicit document size. They wouldn't be called
scalable vector graphics if you couldn't scale them externally. ;)

While you could say a raster image has an intrinsic size (I have no
idea what the formal definition of this phrase is), SVGs *explicitly*
state their size. To change the size, you would actually be violating
the content of the image file itself. I think the best way to
understand this would be to look over what an SVG is. The vectors are
given a scale within the file, not externally.
