TrackClipTypeAttribute autocreate ignored ?

Hi,

I was just reading the TrackClipTypeAttribute source code, and noticed what I'm pretty sure is a bug:

Code (CSharp):

1.     /// <summary>
2.     /// Specifies the type of PlayableAsset that a TrackAsset derived class can create clips of.
3.     /// </summary>
4.     [AttributeUsage(AttributeTargets.Class, AllowMultiple = true)]
5.     public class TrackClipTypeAttribute : Attribute
6.     {
7.         /// <summary>
8.         /// The type of the clip class associate with this track
9.         /// </summary>
10.         public readonly Type inspectedType;
11.  
12.         /// <summary>
13.         /// Whether to allow automatic creation of these types.
14.         /// </summary>
15.         public readonly bool allowAutoCreate; // true will make it show up in menus
16.  
17.         /// <summary>
18.         /// </summary>
19.         /// <param name="clipClass">The type of the clip class to associate with this track. Must derive from PlayableAsset.</param>
20.         public TrackClipTypeAttribute(Type clipClass)
21.         {
22.             inspectedType = clipClass;
23.             allowAutoCreate = true;
24.         }
25.  
26.         /// <summary>
27.         /// </summary>
28.         /// <param name="clipClass">The type of the clip class to associate with this track. Must derive from PlayableAsset.</param>
29.         /// <param name="allowAutoCreate">Whether to allow automatic creation of these types. Default value is true.</param>
30.         /// <remarks>Setting allowAutoCreate to false will cause Timeline to not show menu items for creating clips of this type.</remarks>
31.         public TrackClipTypeAttribute(Type clipClass, bool allowAutoCreate)
32.         {
33.             inspectedType = clipClass;
34.             allowAutoCreate = false;
35.         }
36.     }

the last constructor seems to take an argument allowAutoCreate and then plain ignores it ? Very confused
