RE: Does it effectively lower the cutoff frequency?

I agree with that statement.
Placing any horn in a flat baffle at its mouth controls its polars by a small margin and also provides a bit better loading to the driver to a lower frequency.
A "baffle step" is actually the effect of a flat baffle acting like an 90 degree exit angle horn.
