These system-owned platform task events -- account discovery, check password, change password, etc. are all sent to partition owners. If there are no partition owners then it will send it to the asset admin - otherwise it will only send the notifications to the explicit owners so the asset admin doesn't get flooded with notifications about the world.
NOTE: If Asset Administrators want to be notified along with the Partition Owners, they can set themselves up as an explicit owners or
create an email subscription for the event (for example, IsSystemOwned=false). The API /service/core/v3/EventSubscribers endpoint can be used to create event subscribers for events, including events on specific assets or accounts.
