In case of Exploratory Factor Analysis without any statistical tests you are right. As a matter of fact, Van Ginkel and Kroonenberg (2014) studied this option (averaging a correlation matrix) in the context of pooling the results of PCA, together with two other methods (averaging component loadings and Generalized Procrustes Analysis).

Sure. Exploratory FA is only seldom accompanied in practice by doing statistical tests in it.

But if you enter only a pooled correlation matrix as the input for the factor analysis, then you wipe away all the differences in correlations between the imputed datasets, which is then not incorporated in the statistical tests. It will give you unbiased factor loadings but not unbiased statistical tests.
