should office addin sign out O365 Account When it is authenticated base on O365 authentication?

We are publishing an add-in to office store, and this add-in is authenticated base on the O365 authentication. so Once customer logins his o365 account, he could go to our service directly by our add-in. The question is whether we sign out the o365 account or not we are failed to validate. There are two screenshots:

[Failed if not sign out o365 account]

[Failed if sign out o365 account]

What should we do next step, could we just keep signing out of O365 account and add a note: we are authenticated by O365 authentication when we summit our add-in?
