Councurrent sessions in D365 Business Central

I can read on licensing guide this section:

"Named CALs are assigned on a “named user” basis, meaning each user requires a separate User License; Named user licenses cannot be shared but an individual with a named user license may access the service through multiple devices."

Does the words in bold mean I can access concurrently? If I suppose to have 10 named user licenses can the User1 connect more than one time under the 10 licences? 
Ex.  User1 (PC), User1 (Tablet), User1 (Smartphone), User2 (PC), User2 (Tablet), User3, User4, User5, User6 (Tablet), User6(PC)?

Regards,
Graziano.
