It was really unclear to me too, this example cleared it up:

http://github.com/gron/php-src/blob/PHP_5_3-traits/Zend/tests/traits/bugs/al
ias-semantics.phpt

The current trait implementation does not 'rename' the previous method but
creates an 'alias'.

I think in this case, it would output 'A'.

Personally I would prefer to see:

class Talker {
  use A {
	public function bigTalk();
  }
  use B {
    public function smallTalk();
    public function smallTalk() as talk();  // this 'renames' the function /
not an alias
  }
}

Other example:

class Talker {
  use A;
  use B {
    public function smallTalk() as talk();
  }
}
