So as stated previously, on most sliders all the pins move downward. One pin, usually the bottom one, corresponds to the tape and you use it on longer shots. BUT what most people don't seem to realize is that because the whole housing moves (and consequently all the pins), you can dial each pin to a relatively precise yardage. If you have a 5-pin slider with the bottom pin set to 60 yards, when you dial the 60-yard pin down to 65, all your other pins have also moved down about 5 yards, in other words your 40 yard pin is now at about 45, 50 is at 55, etc. It isn't quite that simple because your 60-70 yard tape distance is greater 50-60, which is greater than 40-50, etc, so there is a little fudge factor. So for 45 your would really dial the 60 yard pin to 64 which puts the 40 yard pin at about 45-46. It isn't perfect and in reality, unless you have a REALLY slow bow, gap shooting out to 60-70 isn't that difficult for hunting, although it is a lot on spots. This is just a more versatile setup if you can sacrifice a little precision and deal with more pins in terms of your vision and brain at crunch time.
