Section 2 says:
This option is an offer, not a promise; both sides must send Window Scale options in their SYN segments to enable window scaling in either direction. If window scaling is enabled, then the TCP that sent this option will right-shift its true receive-window values by 'shift.cnt' bits for transmission in SEG.WND. The value 'shift.cnt' may be zero (offering to scale, while applying a scale factor of 1 to the receive window).
It should say:

Notes:
This need to be left shift
