To my knowledge the LEGO firmware executes one instruction at a time for each task, so there is one and only one instruction being executed at a certain instant even if you have multiple tasks.
Because NQC uses the LEGO firmware, I don't think you can monitor both at the same instant using only one RCX, but I'd love to be proved wrong.
By the way, anyone knows in average how long the firmware takes to execute one instruction?
