Starsky Jr Quetsion

[knotmaker]

I am starting on the Starsky Jr from knitty. my question is on the back part of the pattern is says:

Next Row [RS]: K5[11, 15], work 21-st repeat of Banana Tree Pattern 3 times, k2 [8, 12].

Next Row [WS]: P2[8, 12], work 63 sts in Banana Tree Pattern as set, p5[11, 15].

Continue in patt as set until work measures 9.5[12, 13] inches, ending with a WS row.

Each row of this Banana Tree Pattern has 21st so doe sthat mean you only knit 1 of the pattern rows and then 3 of the pattern rows?????
