For example, when you log in to Yahoo! Chat you will see the following message: \"You are now chatting as your Default alias.\"

You can still switch to any of your aliases, but your Default alias will always be the first one you see. Setting your \"Default\" only affects the names in the account which you are logged in to. The \"Default\" feature will not set the ID that appears first if you are using multiple accounts with multiple Yahoo! IDs on the same computer.
