I suggest you to write a C/C++ program that hides all these terrible 
constructions :-D
and you will get what you want - just one executable for switching 
Touchpad on and off ;-)

here is next iteration, which is more shorter:
synclient TouchpadOff=$(((1+$(synclient -l | awk '"TouchpadOff" == $1 
{print $3}'))%2))
