What would be the reason for that?

That's HTML5 at most.  But imagine what would happen if you simply omitted 
the `checked' attribute.  It's optional, you know.
 
BTW, including a reset button in a form is almost always a stupid idea:

Works great with and without CSS.  NOT.  It's complete utter nonsense; don't 
*ever* do this.  If you don't pre-check any radiobutton of a radiobutton 
group, it will not be part of the request.  There is absolutely no need
to transmit a "hidden" default value for a radiobutton group.

Not that this code would have *anything* to do with the OP's question.

It does not even address the problem.  Would you *please* get a minimum clue 
before making suggestions.
