No, the new class simply extends the old class and can override 
functions in the old class or add new data members and methods.

It can be used to override one method. It's even possible to call the 
old method in your new version:

class ux_someclass extends someclass {

   public function foo($bar) {

     $result = parent::foo($bar);
     $result .= 'extra stuff';
     return $result;
   }
}

This way the code in the original function can change a bit but this 
will not influence the total functionality.

It's not really deprecated. In 4.x versions it relied on some code in 
the end of the original class. This has been removed in 6.x and a new 
method for extending classes has been introduced:
