backpid is given by many extensions and a wellknown parameter. In your 
case it's perhaps differing because its toppid and not a real 
history.back() like you can call with JavaScript. Nevertheless in your 
extension you're free to define that parameter.

In the lefthand navi you want to hide the last point from the menu-array 
depending on your extension. But also the params like itemStates have to 
be changed.
So the easiest and most reasonable way is to implement a userfunction 
that ignores the current pagemenu if the plugin is inserted (and perhaps 
if the parameter backpid is given).
Then you  create a second HMENU inside PHP with the pid of the parent 
page and pass the resulting array to your TS-Menu.
Normally all your queries can be done even without backpid as parameter 
because you can test everything you want inside php and the parameter 
backpid reflects no user-choice but a hirarchical aspect.

Your TS-Menu has nothing special, but doing like I described you never 
need any conditions or other special things, just include your 
php-function ;-)

Best Regards
