Can someone explain the below problem I'm facing?

Consider I have created a user 'test' during Installation which I use to login to my system. My root user is 'root'. I further open two terminal sessions for each of the users respectively. Now the problem is when I type the 'w', 'who' or even the 'finger' command (in my root terminal session) to list all users logged in, I see the 'test' user coming in two times (with different TTYs), which should have actually been 'test' & 'root'. Even If I create a new user 'test1', I still see my original username name 'test' is being the output of w, who, finger commands for users currently logged in. Why so?

PS.: Using RHEL7
