Carpe,
The way to look at this is to consider the Slat position RELATIVE to the flap lever selected position. As another poster pointed out, SLAT2 (as I call it) is the position for both FLAP2 and FLAP3. With the selection of FLAP FULL then you also get SLAT3 ( follow so far?) Thus as far as the table is concerned it may be possible to achieve an aircraft configuration which has Max Slat position + 0 Flap position - hence the relevant speed limit. Very Gallic and not very intuitive!! Hope you enjoy the course.
