In no case can the mere fact that be cited as evidence to support the assumption that there is a causal-effect relationship between A and B. Moreover, that just because B can be statistically correlated with A doesnot necessarily mean that A is the cause of B.

Unless the author can rule out other factors relevant to , this assumption in question can not be accepted.
