Does that mean that I am not really incognito? Can the website see my username even if I don't explicitly log in? O
Incognito means Chrome destroys all cookies created & doesn't record any websites that you visited. The passwords are filled in from Chrome's password manager, not from the site.
Incognito is also a client-side, browser-specific implementation - it doesn't mean no body will be able to track you.
Read Chrome's incognito message:
You've gone incognito. Pages you view in this window won't appear in your browser history or search history, and they won't leave other traces, like cookies, on your computer after you close the incognito window. Any files you download or bookmarks you create will be preserved, however.
Going incognito doesn't affect the behavior of other people, servers
When you go incognito you ask your browser not to identify you to the sites you visit. It does that by (among other things) not exposing its cookies. Exposing the stored username in this mode does not make sense to me (but maybe I'm missing something...).
No, you've misunderstood here. Incognito mode works by destroying the cookies after the session is complete( which is signaled by you closing the incognito window). Incognito does not mean do not identify myself, it means do not keep a track of my activities when I'm on an incognito session.
The thing you are missing is how incognito works - the browser does not present any cookies - that does not mean the browser does not know which website you're visiting - the username/password is fetched by the browser by matching which site you're on - not via cookies.
I can confirm that Incognito Mode does not have access to cookies, auto-fill form data, or WebSQL databases from normal mode. (At least, it does not carry over my GMail session, nor does it auto-fill my email or password into the login form).
As a web developer, Incognito mode is a great way to get an empty browser which provides a clean slate for testing a web page.

Search Engine settings are per user in Chrome and shared with the incognito session.
A workaround is to add a different user profile and simply set the default search engine for that profile.
There is no way to change session from an incognito window, so, you first have to click on the top left hand icon and change users, then launch incognito:
I know this isn't ideal, but it does appear to work.
