For others curious, TSportline responded promptly through their site about the same question: The beam is so flat that it can be for RHD or LHD, unlike the stock lights with an angled "flare" upwards towards either the right or left edges.
Living in a regional area, a stronger, farther-reaching heading beam is attractive to me (I have the LED reflector headlights), but as with the HIDs before, a low-beam sharp cut-off has its pros and cons. I find a bit of light "bleeding" in the LEDs beyond the main focus area, allows me to make out objects that sit higher on the side of the roadway. I speculate that our eyes can accommodate this transition area better than a sudden cut-off between lit and non-lit. However, the trade-off is in the beam's intensity in the hot zone areas and a longer distance.
While I also would like to have seen a video of the MS light in direct comparison, I did find "Everyday Chris" on YouTube who did an extensive comparison on the MY version, comparing it against both the standard reflector lights and the newer projector matrix lights. The author is clear that he is not an expert in lighting but his summary was that Alpharex were close to the newer projector in his testing both on the road and using a simple light meter. The author also liked their look better. It may not be scientific, but the video may be helpful to others:
