If a contact has a primary and secondary email under the Zoho desk accounts, do tickets get associated with them regardless of which email address they come in as?

I was thinking of setting a contact primary email as:

secondary email as:

So that when this particular contact sends in a ticket (a form based submission), that it would not send a notice because the primary email is no-reply@example.com but still associate tickets with that contact when they're sending from actual.email@example.com.
