It seems to be a Boeing tradition. The main jacking points on the 747, 767 and 777 are located under the forward spar of the wing at the root. The C of G is aft of the main jack points and thus, the "tripod" of jacks formed by the main and tail jacks can support the entire aircraft off the ground (weight distribution and limits apply of course).
The 747 has five additional stabilisation jack points, one at the nose, and two points along the span of each wing. IIRC, the Airbus arrangement has the two main jack points located on the rear spar, which make a stable triangle with the nose jack. What is amazing with this arrangement is how far away from the root that the main jack points are, as they are located outboard of the main landing gear. The bending moment on the wing must be huge!
