EDGE Save password loss issue

I found that when a user's Microsoft account has two aliases, there is a way to manage your login Microsoft in the account information, and two email aliases can be set in it. Suppose an account has two aliases email address removed for privacy reasons and email address removed for privacy reasons, and the password synchronization option is enabled email address removed for privacy reasons logged in on one computer, and the password synchronization option is also enabled email address removed for privacy reasons logged in on the other computer. This can cause password loss issues. email address removed for privacy reasons saved password will be overwritten by email address removed for privacy reasons. If the EDGE of the computer where the email address removed for privacy reasons is located is not commonly used, the password saved by the EDGE of the computer where the email address removed for privacy reasons is located will be lost. Is this a BUG?
