Replies to more than one user

When you are writing a note to more than on user, for example

    @x @y @z how are you?

This note doesn't appear in the "Replies" section of any of the three users.

However, if you only write: @x how are you? , this note appears in the Replies of @x

I think that the first note should appeard in the "replies" of the three users.

Thanks again!
