Normal. There's a small dead length at the two ends of a string that don't actually vibrate like the rest of the string does. The thicker the string, the longer that dead length is. Which is why the distance from the 12th fret to the bridge is always going to be longer than the nut to the 12th fret. Double the nut to 12th fret distance determines the scale length, but because of the two non-vibrating bits of the string, the overall distance from nut to bridge saddle is always going to be longer in order for the bass/guitar to intonate properly. And because the strings are all different thicknesses, that's why the saddles all end up in different positions when the intonation is set.
It's the diameter of the core wire of a string that mainly determines the 'dead' length of a string, the wrappings mainly add to the mass per unit length. Which is why on a guitar, the wound D string saddle is normally further forward than an unwound G string saddle - its core wire is thinner than the G string.
