No it hasn't. It's 486 visible lines, of which a few often get lost off the top or bottom; most people round off as 480 lines and 640 columns actual viewable area.
You're measuring the height. The width is 720. When transcoded for a computer, it is often scaled to 640x480 for square pixels.
What do you think 720i means? The height, not the width.
