Server Location of Individual Mailboxes are Different

Currently we are using 2 Exchange 2013 servers to host our mail.  I have set up a Database Availability Group (DAG) between both servers (I will refer to them as SRV1 and SRV2).  I was using the Get-Mailbox cmdlet and noticed a strange discrepancy.  

Even though SRV2 is storing all active copies of our databases, some mailboxes are showing SRV1 as their server according to the Get-Mailbox cmdlet.  Would there be a reason for this?  I have created all mailboxes on SRV2, it just seems strange to me.

Check which database the mailbox is created and then which server is holding that database now. Since you are using DAG, database may fail over to the SRV1 server in case any issue with SRV2.

All mailbox databases currently have their active copy on SRV2, yet some mailboxes are showing SRV1 as their server.  It's only a handful but still very puzzling.
Probably it refers to the server the mailbox database was on when the mailbox was created in that store... Check this related post from MS forum..

when run get-mailbox for a user mailbox , returns old server name was removed from the DAG !

Although the link appears to be referencing Exchange 2013 I haven't been able to come up with a better answer and this would appear to be the case.  Thanks for the help.
