The phase relations are determined by the math. Here's two graphs that show the difference between a symmetric 1st order crossing at 800 hz and an asymmetric 1st order also crossing at 800 hz.
With the symmetric the phase difference is a constant 90 and the output of normal polarity and inverted polarity are superimposed on each other.
With the asymmetric, the phase difference varies with frequency and the normal polarity creates a dip while the inverted polarity has a much shallower dip.
