Ahhh, the advantage of a digital. Once the power is turned off there's no further hold from the servo so it follows the weight or resistance of what it's connected to. OTH, once the servo is powered up again it will go pretty much exactly to the position commanded by the TX/RX. If that position happens to be in the same place as when the servo was powered down, the servo goes there with 100% of it's rated strength.

However, an analog servo is sort of unsure of itself most of the time, has a lower resolution which makes finding the last position and center considerably more difficult, and has about a 7 degree variable built into the gear train at the control arm. It achieves rated torque only after traveling though about 60% of its rotational distance. It will try real hard but it has soooo many performance deficiencies built into it and those are hard to overcome.
