blender 2.71 sample all lights - twice in gui why ?

blender rc1 2.71; what is the difference between the upper and lower Sample al lights ??

oops …its in the discription direct vs indirect … maybe someone think over this GUI element.

Uh, that’s not their names. How tiny IS your properties window?

Although I suppose the names could be “Indirect Sample All” and “Direct Sample All”…
