Border-radius in SASS version

[frabenanti]

There is a problem with SASS version.
Sometimes is used border-radius mixins with only 1 value ( @include border-radius(4px); in _buttons.scss ) and the output is with only 1 rounded border:

-webkit-border-top-right-radius: 4px;
-webkit-border-bottom-right-radius: 0;
-webkit-border-bottom-left-radius: 0;
-webkit-border-top-left-radius: 0;
-moz-border-radius-topright: 4px;
-moz-border-radius-bottomright: 0;
-moz-border-radius-bottomleft: 0;
-moz-border-radius-topleft: 0;
border-top-right-radius: 4px;
border-bottom-right-radius: 0;
border-bottom-left-radius: 0;
border-top-left-radius: 0;

Would'nt be better to use @include rounded(4px); ?
