As seen in the comments email copies should only be sent as separated emails if their copy method is copy.

Steps to reproduce: (*)

1. Go to Admin -> Stores -> Configuration -> Sales -> Sales Email -> Order Comments and set Enabled to Yes
2. Add email address to Send Order Comment Email Copy To
3. Set Send Order Comments Email Copy Method to Bcc
4. Place order.
5. Add order comment in order overview (adminhtml area) and uncheck notify customer.

Actual Result: ✖️ a copy of the email was sent

Expected Result: ✔️ Email copy should not be send because notify customer is disabled and copy set to bcc.
