That's the main thing, but not the only thing.
WebGL is also very portable, more than other flavors of GL. Huge effort has gone into that. As a result there is a much better chance a WebGL app will give the same output on different browsers/OSes/GPUs (and if it does not, that's a bug that should be fixed).
WebGL is also more secure than OpenGL, since it was designed to run in a web browser, that executes unsafe code off the web.
