Will changing the owner account's email cause it to merge with existing editor account?

[CCDems]

Hello,

I have a Weebly account, "a@mydomain.com," that owns a website and a separate editor's account, "b@anotherdomain.com," for that website.  I want to merge both accounts and set "b@anotherdomain.com" as the website owner. 

Is it as simple as going to the owner account's settings and changing the email? 

Thank you.

Answering my own question:

When I tried to change the original owner's account, I got an error message stating that the new email address was already in use. So, I had to change the "b" account to a third email address, "c@thirddomain.com," before I could go back to "a" and change the account's email address to "b".
