Cookies are still stored and shared among other Incognito tabs. This makes Incognito more usable: you can login to an online store, open a few product pages in new tabs, add items to your cart from all these tabs and check out in the end. If each tab had its own cookie store, they'd have separate carts as well. AFAIK, you need to close all Incognito tabs for the session to end.
