Narrative:

Taxiing on mia airport and holding short of runway 9L behind a delayed B727. I was told to pull up and hold on the left side of the pad. The B727 was waiting at the hold short line, so I thought ATC wanted me to pull up in front of him. After I pulled up, ATC told me to hold where I was. Upon reflection, I am not sure if he wanted me in front of or behind the hold short line. Better communication would have helped.
