This is a coincidence.  Binary data contains three vertically
interlaced copies with vertical offset.  If you get every 3rd bit and
assemble it into image again, you will get scanned data (little more,
actually, as hardware line width in this particular case is 384 bits,
not 288).  Incidently, 384=3*128.

It seems that epkowa uses 2nd copy (counted from 1).
