Butterworth filter bandpass order 1

WebI have now read that a 6th order bandpass filter is enough, which diverges from my knowledge. I thought that a butterworth had a roll-off of 6 dB/octave, per order. Looking a MATLAB's Filter designer: This pictures shows a 6th order bandpass, butterworth IIR filter. It also shows a attenuation of ~48 dB, 1 octave above Fc2. http://msp.ucsd.edu/techniques/v0.11/book-html/node147.html
