Issue with Bitbucket user access

Question

I have created 2 Bit-bucket accounts by using 2 different email addresses.

Bit-bucket Repo 1 : 1234@gmail.com Bit-bucket Repo 2 : 5678@gmail.com

I pulled the files using Repo 1 using Git Bash. At that time it asked me to enter the credentials and it worked correctly. Then I closed the Git Bash and pulled the content from the Repo 2. At that time it didnt asked me the credentials. I was able to commit and pull the files without having any issue.

But after visiting to bitbucket.org and my project repository I was able to see these commits. (Refer Image 1)

It says 'harsha' not mapped to Bitbucket user. If its not mapped and if its not in repository permission list, How it was able to push the changes in to the repository? Only the below users have access to the repository.
