Narrative:

I arrived at runway 36 at taxiway G. Told tower 'aircraft X ready at 36 golf.' was told to hold short for landing traffic. Responded 'holding short at 36 golf.' I heard tower tell an aircraft to 'position and hold.' I thought the clearance was for my aircraft, but was actually for another aircraft. I responded, 'position and hold for aircraft X' as I rolled past the line. As I rolled forward, I looked for landing traffic and saw an aircraft. At the same time I heard tower tell an aircraft to go around. I did not get out onto the runway. I was approximately 15-20 ft past the line. I was monitoring multiple radios and airspace was busy at the time, as well as the ground traffic. The passenger next to me was talking to me. I should not have rolled forward until tower responded to my reply of 'aircraft X, position and hold.' I might have transmitted over wrong radio. When I returned from short flight, tower asked me to call on telephone when able. I did and supplied them with requested information.
