Does it sound like I’m not doing well in my new job?

Next month will mark the end of my 3 month probation period. Last week, my boss told me that I’m doing very well but she thinks I should take initiative in certain things versus doubting and asking for her reassurance. She said that when it came to a certain aspect of the job, I caught on quicker than others. I’ve gotten good feedback, the job requires presentations and public speaking terrifies me but the classes are smaller. I had to host 2 employees today virtually and then she/the other coordinator came in at the end to ask for feedback from the class. I was at the front sitting because I hosted the virtual go to meeting but sat in my seat for both of those presentations. She said next time, to stand up and show authority at the end, when she and the other coordinator came in to talk. I got kinda defensive and I know she said to do that last time when we did the last session but today was my first time hosting and I thought that sitting at the desk in front of the classroom was enough, I was sitting in the back as the other coordinator hosted it last time. She said I did very well but that’s all she would add.
