Does Internet Explorer 11 Enterprise Mode supports IE9, IE10 besides IE8?

When I set "IE9 DocumentMode" in Enterprise Mode Site List Manager, restart IE11 the console still shows that it's working in Internet Explorer 8.

I want to know if EMIE supports IE9 and IE10. See below in this article:

Sites can be added to the Enterprise Mode Site List to fix compatibility problems with sites originally written for IE8, IE9, or IE10.

Technically, IE11 in EM is an emulated IE8 which is why it still shows as IE8. This is also evident in the user-agent string if you try to sniff it. The rationale behind why EM chose IE8 as the engine can be found in this blog post:

Internet Explorer 8 still has more than 20% of the desktop browser market share; despite the fact that IE9, IE10, and IE11 have superseded IE8, many customers still rely on Internet Explorer 8 to run their business.

If you have set your document mode to be anything higher than IE8, then it will eventually fallback to the emulated engine. Look at last paragraphs of page 14 of this Internet Explorer Standards Support Documentation Overview:
