Transfer account to someone else

I recently started the process of transferring my account to a roommate and I received the ACCOUNT CHANGE REQUEST FORM but I have a doubt about a checkbox that says the following: "Transfer this account to a new account holder (includes equipment and/or access to email and voice mail)"

Is that my personal email that I set up for my account? Are they going to have access to it? Can someone explain to me please, thank you.
