Wyckoff: how to distinguish a re-accumulation from a distribution (and vice versa)?

I started studying Wyckoff because of it’s solidity during market movements.

But I have an unanswered question that internet cannot answer: how can a trader distinguish a re-accumulation from a distribution, or a re-distribution from an accumulation?

​

FYI

This is a re-distribution

re-distribution

and this is an accumulation

​

accumulation

and THIS is what triggered me to post this question:

Wasn’t this supposed to be an accumulation? Where is the Signal Of Weakness? Why is there a Signal Of Strength? It has every match for it to be an accumulation, but it resulted in a re-distribution instead.

Any help is appreciated.
