corrected notation
Interception line changes are immediate - the juggler and manipulator swap line before the next beat. So, even if it is a 1 beat intercept with a line instruction after it, the juggler and manipulator change lines first, then read the line change instruction afterwards. They follow both instructions, but the order is important. So if a manipulator line showed at the end of the line: iB => M the juggler who was B up until the last instruction becomes M because of the intercept (iB) and then they stay M because of the (=> M).
