Narrative:
Ground advised us to taxi to hold short runway 4L and to follow air carrier Y B757 to runway 9. Ground advised us to contact tower 128.8. Tower instructed us to follow air carrier Y B757 to runway 9. Air carrier Z B737 landing on runway 4L questioned if they were still to land on runway 4L. Tower advised yes. This made us unsure of our taxi clearance.
