FORUMDISPLAY CSS Class Duplicated? What?

[vaskies]

.above_threadlist_controls {
	margin-top: {vb:math {vb:stylevar padding}/2};
	float: {vb:stylevar right};
	clear: both;
}
 
.above_threadlist_controls {
	display:block;
	width: 100%;
	border: {vb:stylevar forummenu_border};
	background: {vb:stylevar forummenu_background};
	_background-image: none;
	margin-top: {vb:math {vb:stylevar padding}/2};
	margin-bottom: 0;
	position: relative;
	-moz-border-radius: {vb:stylevar forummenu_border_radius};
	-webkit-border-radius: {vb:stylevar forummenu_border_radius};
	float: {vb:stylevar left};
}

What confuses me further is the first class floats right, while the second class floats left. Did I inadvertently do this myself or is everyone else's forumdisplay.css like this?
