Can't give you the math, but the hypothetical might be that before JML on either side goes, lets say JKR1 is at 80% TM, and JKR2 is at 90%, since JKR2 is faster. JML1 puts JKR1 at 95%. Assuming JML2 hits 100% before JKR1 does, he puts JKR2 at 105%. Even if JKR1 is at 100% at this time, JKR2 has more 'overflow', so gets next turn.
This is a very simplified example, but basically as long as JML2 gets to 100% before JKR1, its LIKELY his TM boost puts JKR2 'above' 100% TM before JKR1 gets there.
At least that is my understanding.
