I also have a Toyota hybrid. Regenerative braking falls off as speed decreases. Whatever algorithm they use to determine how hard to apply the brake pads either doesn't compensate for this or is tuned conservatively. I don't think this is too much of a problem. But there's another failure mode that will startle you unless you're monitoring the battery charge on long downhill slopes. If the battery gets too full, the regenerative braking cuts out abruptly. If you're dealing with this kind of terrain regularly, you might want to get familiar with the engine braking mode. (B or S on the shifter)
