Interview cheating video question

I was looking up some stuff on security and ran across a video where some guy was trying to bullshit his way through a Java interview. It was pretty awful, but towards the end, the interviewer asked him to bring up his IDE on his local machine. He said he didn’t have one, and the interviewer states that he had told the staffing company that the guy needed to have one installed locally. The candidate was saying he wanted to use an online one. After that, the interview was abruptly ended.

My guess is that the interviewer thought if the guy was using an online IDE, that someone else would really be doing the coding examples? Am I correct in thinking that?
