I think current bi-amp configuration leans more toward horizontal than vertical. That is using one amp per channel (monoblocks), instead of splitting the upper and lower frequencies.
As randy said, it allows an amp to drive less of a load-which would be very advantageous when connected to inefficient speakers.
Using two monoblocks also let you place the amps close to the speakers, so you don't need long runs.
