That's a strange instrucation. That only thing I can think is that it's just another way to say simple M1. In order to M1, you have "open" the bar btw the 2 sts in the row below... :thinking: Is that pattern online by any chance so we can take peek??
Check out this
page to see how to "M1"... it's near the bottom of the page. You'll see M1F and M1B.
