Doesn't a high refresh rate kind ruin one of the big benefits of e-ink in the first place?

The reason I liked e-ink is because the screen only refreshed on a page change, so unless you're using the back light, the main power draw is turning the page.

Yes and no. Even when refreshing rapidly the power draw is still significantly lower than something like an LCD, but not as low obviously as when refreshing slowly. It is nice to have the option of a high refresh rate if needed occasionally, but since every eink display I've seen with it to date suffers from absolutely horrendous ghosting when doing so the utility is highly questionable. Lets just say I am very skeptical of that claimed 30 Hz refresh rate and highly suspect it's impractical marketing BS.

Yeah, that power metric can fluctuate wildly depending on how smart their display controller is. Throw VRR and / or event driven rendering into the mix and you get most of the benefits of both with the added benefit of limiting rendering bursts.
