The first one, known as Preta Path, could absorb the chakra on touch, as well as the techniques, via Blocking Technique Absorption Seal. The problem is that technically you have to touch the person/technique to suck chakra in, while Sasuke was immobilised and thus unable to touch the shadow on the ground. Momoshiki's absorption is seemingly able to suck chakra and techniques in without the need of directly touching them, it's just enough to have them nearby.

However, I must admit that it doesn't exuse Sasuke's inability to absorb ninjutsu Momoshiki was constantly throwing on him and the other opponents, especially on the chunin exam arena.

Actually when preta path is used, a sphere forms around the user and any jutsu that interacts with the sphere gets absorbed like so: Preta Path. That how I think sasuke should have been able to escape.
