Narrative:

I was taxied up to the ILS hold line for runway 17 at phl. I monitored phl tower frequency and I heard him clear another aircraft behind me for an immediate takeoff. As the aircraft skirted around me from behind, I told the tower that I too was ready for departure. The tower then told me to taxi and hold, upon which I repeated his instructions by telling him that I was going into position for runway 17. After being in position for 3 mins, an small transport flew over me at 20' clearance and landed. I then talked to the tower and he told me that he had only instructed me to taxi and hold at the next hold line. I never for a minute doubted the tower's instructions because I repeated them back to him.
