Forcing users to login again, ramification on sessions

When you force a user to login via passing prompt=login as a query parameter when making the login request, what happens at the Auth0 authorization server session-level?

For example- Say you have two different applications leveraging the same Auth0 authentication domain AND the same user can potentially have a different email address in each… if a user authenticates in both, with different emails, does that create two sessions? Or does the first one get revoked?
