That is what I would expect. When a timer fires, interrupts any other fox code running, even code running on other timers, something like:
Timer1
Code...
<Timer 2 Fires> Timer2
Code....
<Timer 3 Fires>
Timer3
Code...
<Finishes>
<Timer 2 continues from where it stopped>
<Finishes>
<Timer1 continues from where it stopped>
