Bug on crop_from_position function?

Is it possible that there is a mismatch of the array index in the crop_from_position function in wpthumb.php:

if ( $position[0] == 'bottom' )
	$crop['y'] = absint( $size['height'] - $height );
else if ( $position[1] == 'center' )
	$crop['y'] = intval( absint( $size['height'] - $height ) / 2 );

if ( $position[1] == 'right' )1
	$crop['x'] = absint( $size['width'] - $width );
else if ( $position[0] == 'center' )
	$crop['x'] = intval( absint( $size['width'] - $width ) / 2 );

Changing in these lines the array indices as seen below lead me to a correct visualisation of the images

if ( $position[1] == 'bottom' ) // changed index 0 to 1
	$crop['y'] = absint( $size['height'] - $height );
else if ( $position[1] == 'center' )
	$crop['y'] = intval( absint( $size['height'] - $height ) / 2 );

if ( $position[0] == 'right' ) // hanged index 1 to 0
	$crop['x'] = absint( $size['width'] - $width );
else if ( $position[0] == 'center' )
	$crop['x'] = intval( absint( $size['width'] - $width ) / 2 );
