I would reverse the question and ask what would be the reason to have
multiple input parameters used for Schedule construction instead of
just passing a Schedule, that is a single parameter.

Besides it is not rare the case in which the schedule used for the
bond might have been originated from a swap, or viceversa

I don't have access to the code right now, but if I remember right the
input frequency is used in order to calculate the actual coupon
payment from the coupon rate, and it might be different from the
frequency used to calculate the yield, e.g. when you want to compare
the yield of 2 bonds with different coupon rate frequency and/or
schedule

hope it helps
