CSS question

Making the upgrade I noticed that the comment for margin-right in layout.css doesn't match it's calculated value. Not sure if the comment or the value is wrong?

#content,
.no-sidebars #content
{
float: left; /* LTR */
width: 940px;
margin-left: 0; /* LTR */
margin-right: -960px; /* LTR */ /* Negative value of #content's width + left margin. */
padding: 0; /* DO NOT CHANGE. Add padding or margin to #content-inner. */
}
