quote............."The pontil mark looks to have tool marks (I may be wrong)"...........
I believe the expression 'tool marks' refers usually to those lines around the bowl or foot - caused by tools that the maker used to form the shape. Can't see too clearly, but the marks to which you refer might just be the remains of the air spiral as it exits the underside of the foot - or alternatively some remnant of the pontil scar which hasn't been neatly ground/polished out.
