Chugging up hills in the low and mid range gets you to the top.
What you just said is: "Reducing power output improves traction." Duh. Increasing mass/inertia has a similar effect as reducing power output. The counterbalance increases inertia. All of us dirt bike riders know that a higher-inertia motor of the same hp will 'hook up' better than a lower-inertia one. We may or may not be able to recognize the reason behind it, but our observations show it clearly. It has zip to do with firing interval on a single.
We must be careful that we don't confuse a well-designed overall package with a somewhat unusual firing arrangement. This is marketing trying to play up a frankly very small thing, masquerade it as something it's not, and use it to drive sales. I'm glad it's working for Yamaha. It's not working to beat the 'flat-plane' Hondas on the track, but I hear it's working on the showroom floor, where myth works better than fact.
