It hadn't been moved sideways, just pushed down a bit.
That would suggest the lie was altered so 20-3b applies
[h=4]b. Lie of Ball to be Placed or Replaced Altered[/h]If the original lie of a ball to be placed or replaced has been altered:
(i) except in a hazard, the ball must be placed in the nearest lie most similar to the original lie that is not more than one club-length from the original lie, not nearer the hole and not in a hazard;
You then say "... we did replace the ball as near as possible to what we estimated to be its original lie and position ..."
Sounds OK to me.
