Yes, clicking that button will launch it in Modern UI mode, other than that it is the same.
If you're wondering how to always launch in Modern, then I believe you have to check that as a setting when you install it.
Please be more specific with your question.
My appologies. That wasn't a question. It was showing you how to launch it, a mini tutorial I suppose. Clicking that option will always launch in it in the UI until you click it again from the UI which then says "Relaunch Chrome on the desktop."
