I had to break out the instructions to be sure - I believe after reading them that the syringe tip is not directly used in calculating the volume, but since some titrant remains in the tip when fully depressing the plunger, it is essentially a filler taking up the "void" space.
The kit indicates that there should not be any air bubbles in the syringe when filling it from the titrant bottle. After ensuring that the bubbles are removed, it instructs you to pull the plunger up to the 1.0cc marking. It later states "Once true blue color is obtained, withdraw into the syringe any titrant hanging from the tip of syringe so that titrant is flush with the tip before reading volume of titrant used in titration."
