That is true, but it does not solve the problem. Using different names 
for radio buttons makes them isolated so that each of them is a group of 
its own. Then, once the user checks a radio button, he cannot uncheck 
it, because the only way (in HTML) to uncheck a checked radio button is 
to check another button in the same group. Moreover, this does not make 
it mandatory to check at least one of the buttons - you would still need 
to check that on form submission, just as in the more natural approach 
that uses checkboxes.
