Patterns to do before this one
As with all Jim's pattern, they are easier to describe as a half-synchronous pattern, where both jugglers have a throw at the same time (but some passes arrive early and force a hurry from the wrong hand), but are easier to juggle as an asynchronous pattern.
Explanation based on regular n-count: see Jim's 4-count. (The explanation is the same, just with a different amount of selfs)
Asynchronous pattern sequence:
A 1|2: P F S P S B 1|2: P S P F S
You can juggle the pattern either with a flip or if that makes it too difficult you can skip the flip and just hold the club for that beat.
