Nah, just the American tendency toward bigger-is-better, which works up to a point. I suppose the next size up from Canyon would be called an Oceanic
Here's another speculation on what they might mean by "reverse rollover." Perhaps if the water level is just right (i.e. less water than a conventional TL, which could be the water conservation aspect they're promoting), the disc causes the entire mass of water & clothes to move in a circle that coincides with the axis of the disc? That would require a slow long stroke with a brief pause between reversals. The turnover would be less rapid than with conventional agitation, and much of the cleaning would be done at the bottom of the tub where the water currents were most vigorous. Could be effective, but also potentially very splashy.
BTW, I did check out the link above. -> About Oasis -> Cleans better: shows a slow-motion animation or series of sill pics with one white item among a bunch of dark items, but I still can't figure out exactly what's going on.
And now that I think of it, interesting that they have a little *boy* looking into the machine: breaking down the old stereotypes about girls and housework, and/or maybe playing off the idea of boys being into interesting mechanical stuff (i.e. implied: this is so mechanically innovative that boys find it interesting). The same little boy turns up in another picture, sitting on the clear lid while mom is picking up a laundry basket. (Implied: Yes, the clear lid is strong, look, your kid can sit on it without breaking it.) In fact there's yet another shot of the same kid looking into the dryer: he's got a soccer ball in one hand, and his sneakers are apparently sitting on a removable shelf that's been put in the dryer to dry them. (implied: but this boy's not an indoor-kid, see, he plays outdoor sports!)
