Narrative:

Cleared to taxi out of gate inner B to B, hold point runway 27. Held at B hold and monitor tower. Tower cleared us B/south position runway 27. We had our taxi chart open and available and looking for south crossed 27. At the time aircraft were departing on 4L from east and 4R from B. Our clearance was position and hold runway 27 via B/south, traffic 3 mi final for 4L. Both the first officer and myself visually checked the approach and departure paths and saw no conflict. This report is to note confusing clearance and markings at this point on the boston airport. There was no conflict and we taxied into position via S1 to runway 27 when I now believe ground wanted us into position via B. Callback conversation with reporter revealed the following information: reporter spoke from memory and thinks he taxied via B across both the runway 27 and runway 22R stopways and then via S1 to runway 9. In his report and during callback, he referred to using runway 27. He seems to have been confused. He said tower made no big deal of it and said there was no problem.
