Having just layed it out manually, doing this gets the result you want:

- Create a grey filled square (RGBA 128,128,128,255)
- Overlay that with a square with gradient from top-right to bottom left
RGBA 255,0,0,255 -> RGBA 255,0,0,0 -> RGBA 255,0,0,0 (i.e. with the alpha
set to 0 at the _mid-point_)
- Do the same with a gradient from bottom-left to top-right RGBA
0,255,255,255 -> 0,255,255,0 -> 0,255,255,0
-> top-left to bottom-right RGBA 0,0,255,255 -> 0,0,255,0 -> 0,0,255,0
-> bottom-right to top-left RGBA 255,255,0,255 -> 255,255,0,0 -> 255,255,0,0

That pretty much duplicates the example you posted.

To get all that in ActionScript, look up MovieClip.beginGradientFill() in
the docs - combine it with moveTo() and lineTo() and it should all be fairly
easy.
