Visual studio feature - commenting code Ctrl K - Ctrl C

I commented on this answer some time ago regarding how visual studio comments out code with // or /* */. I was thinking to revise the answer (to include my findings) but I had to test it first, which kind of confused me.

My finding is that depending on what you comment when you press Ctrl - K, Ctrl - C you will get either // or /* */.

First example:

<start selection here>    code();
                          someCall();
                          thirdCall();<end selection here>

this will produce the following:

//code();
//someCall();
//thirdCall();

Second example:

    <start selection here>code();
                          someCall();
                          thirdCall();<end selection here>

this will produce the following:

/*code();
someCall();
thirdCall();*/

Third example

    <start selection here>code();
                          //someCall();
                          thirdCall();<end selection here>

this will produce the following:

//code();
////someCall();
//thirdCall();

Note that example 2 and 3 is the exact same selection, but the comment makes Visual Studio interpret it differently.

Why is this?

The approach one would expect is to use // for any selection that is made up entirely of complete lines, and /*...*/ for anything that starts/ends mid-way along a line.

...which is what it seems to actually do.
