This is a difference in the subject of coherence.
Logical coherence refers to the variation and predictive power of the reasoning.
Coherence can also be used to describe the variability and predictability of positions or states themselves.
If you measure the characteristics of some photons in a coherent laser, you know what the other photons are doing. They are predictable using a model.
Logic is a poor predictive model for politics. Tribe identification is a strong predictive model for politics
