Resources.LoadAll docs

hey the docs for Resources.LoadAll(); gives the following example:

Code (CSharp):

1. // Loads all assets in the "Resources/Textures" folder
2. // Then picks a random one from the list.
3. // Note: Random.Range in this case returns [low,high)
4. // range, i.e. the high value is not included in the range.
5.  
6. using UnityEngine;
7. using System.Collections;
8.  
9. public class ExampleClass : MonoBehaviour {
10.     void Start() {
11.         GameObject go = GameObject.CreatePrimitive(PrimitiveType.Cube);
12.         Texture2D[] textures = (Texture2D[]) Resources.LoadAll("Textures");
13.         Texture2D texture = textures[Random.Range(0, textures.Length)];
14.         go.GetComponent<Renderer>().material.mainTexture = texture;
15.     }
16. }

to my experience this doesn't not work, is that correct?
the following does however work:

Code (CSharp):

1. // Loads all assets in the "Resources/Textures" folder
2. // Then picks a random one from the list.
3. // Note: Random.Range in this case returns [low,high)
4. // range, i.e. the high value is not included in the range.
5.  
6. using UnityEngine;
7. using System.Collections;
8.  
9. public class ExampleClass : MonoBehaviour {
10.     void Start() {
11.         GameObject go = GameObject.CreatePrimitive(PrimitiveType.Cube);
12.         Texture2D[] textures = Resources.LoadAll<Texture2D>("Textures")as Texture2D[];
13.         Texture2D texture = textures[Random.Range(0, textures.Length)];
14.         go.GetComponent<Renderer>().material.mainTexture = texture;
15.     }
16. }

is this the general experience with LoadAll? if so maybe the docs could be updated to this.
it didn't take that long to find out but still it's wasted precious development time.
