Home theater crossover question

I mounted my surround side speakers on the wall, so I used my Onkyo TX-SR803 receiver's auto configuration feature. I went into speaker setup when it was done and looked at the crossover settings, and now I have a question.

It set the front speakers to 200hz and the subwoofer to 120hz. Assuming the front speakers send everything under 200hz to the sub and the sub only goes up to 120hz, does everything from 121hz to 199hz get lost? Shouldn't the speaker crossover point be the same as the sub? Thanks.
