Some seem to be mixing up two things and associate the wrong things to "midi drums":

"Midi drums" does NOT necessarily mean that the drum rhythm is generated by a machine instead of a human being.
Like you record an audio drum sequence from a real drummer, you can record a whole sequence played by a real drummer the same way via midi when a good midi drum set is used.

The problem with arranger styles is that the manufacturers haven't invested in drum sessions with a human drummer - but it wouldn't be necessary to go as far as to record "audio" drums - midi drums would create the real feeling as presented in the video above - but then you could STILL edit it afterwards.
