PVS-Studio warning V562 for blender

#define MAX2(x,y) ( (x)>(y) ? (x) : (y) )

static Scene *preview_prepare_scene(....)
{
  ...
  int actcol = MAX2(base->object->actcol > 0, 1) - 1;
  ...
}

Most likely this is what should be written here: int actcol = MAX2(base->object->actcol, 1) - 1;

This suspicious code was found in blender project by PVS-Studio static code analyzer.
Warning message is:
V562 It's odd to compare 0 or 1 with a value of 1: (base->object->actcol > 0) > (1). bf_editor_render render_preview.c 361
