When you migrate a user from domain A to domain B, SharePoint 2016 does store SID history. With SID history, a user would continue to use their old account to access SharePoint until the old account is disabled in AD, the new account is enabled and their account has been migrated within SharePoint (Move-SPUser). From that time forward, the user would only use their new account to log in and access SharePoint.
It's recommended that you remove SID history once the migration is complete.
