There's no way to resolve a path containing some \..\ to go to the previous folder.
In this thread :
https://forums.mirc.com/ubbthreads.php/ubb/showflat/Number/230726/ it's mentioned and I state that .. in path works everywhere.
Well $sfile does not support .. in path, and it would still be great to be able to get full path.
$samepath could be extended with two prop .path1 .path2 to access either value but resolved instead of returning a bool value but it's possible to do this with $file and a new prop there as well.
