how about same methods in C and C1?

this is some hard to understand 
and I can't find example in docs

Unexpected redefinition last(?)-trait method to class method

Test script:
---------------
<?php

trait ATrait {
    public function a(){
        return 'Aa';
    }
}

trait BTrait {
    public function a(){
        return 'Ba';
    }
}

class C {
    use ATrait{
        a as aa;
    }
    use BTrait{
        a as ba;
    }
    
    public function a() {
        return static::aa() . static::ba();
    }
}

$o = new C;
echo $o->a(), "\n";

class C1 {
    use BTrait{
        a as ba;
    }
    use ATrait{
        a as aa;
    }
    
    public function a() {
        return static::aa() . static::ba();
    }
}

$o = new C1;
echo $o->a(), "\n";

class D {
    use ATrait{
        ATrait::a as aa;
    }
    use BTrait{
        BTrait::a as ba;
    }
    
    public function a() {
        return static::aa() . static::ba();
    }
}

$o = new D;
echo $o->a(), "\n";


Actual result:
--------------
AaAa 
BaBa 
AaBa
