A UNIQUE NEW TYPE OF STYLES FOR ARRANGERS

...
This provides unique and new possibilities in style creation that have not been seen before.
Wersi is the only brand that does this, and conversions from this give us musicians new opportunities.

This is not really true. I don't own Korg, but to my knowledge that's the purpose of Chord Variations (CV). And even Yamaha doesn't officially support that feature, this can be done on Yamaha as well.

Korg advantages:
-it's official feature and can be done on keyboard
-in each variation (MainA to MainD), there can be up to six chord variation in each channel. For intro/ending only major and minor are supported, if I remember correctly.

Korg disadvantages:
-if I understand CV correctly, then all CV's on particular channel can only use the same one voice.
-I'm not sure, but I think not all chord types are implemented (i.e. sus2, sus4).

Yamaha advantages:
-all chord types can be used
-if needed, each chord variation can have different voice (is quite useful!)

Yamaha disadvantages:
-in one variation (for example, MainA) we can only have max up to eight chord variations in total (it's up to user on which of eight channels they will be used). So far I personally never needed more chord variations, but would be nice to have more.
-there's no official documentation and so it can be considered as unsupported (although Yamaha is using that feature in all built-in styles).
-while different chord sequences can be created on keyboard, on keyboard we cannot make them to actually work as chord variations. To accomplish that, the style (CASM section) must be modified on PC.

I hope you find that informative
