Visual Studio 2015 behavior in nested using statements

From a similar question asked before , it is known that the preferred way of deferred nested statements using

(this is the default preview of Visual Studio 2015):

using (var enumerator1 = list1.GetEnumerator())
using (var enumerator2 = list2.GetEnumerator())
{
    // Use enuemrator1 and enumerator2 here
}

      

        
        
        
      

    

However, I found that the behavior was changed in Visual Studio 2015 when I type the following:

using (var enumerator1 = list1.GetEnumerator())

      

        
        
        
      

    

and click ↵, the cursor is indented on the second line:

using (var enumerator1 = list1.GetEnumerator())
    ‸ // Text caret appears here instead of at the same level of
     // indent of the previous line

      

        
        
        
      

    

How can I return the previous behavior and what is the reason for changing this behavior?
