Close, at least: SEPIC, Cuk and Zeta converters are related by which way the supply/load is connected.
Cuk has the unique distinction of continuous current on both nodes, and the disadvantage that the input and output are opposite polarity.
As you probably guess (and have neatly drawn, as if to suggest this very point..!), this does not have continuous current at the supply; rather, it is pulsed, so that the bypass capacitor is required, not just nice-to-have. This is an example of the (drumroll please) Zeta converter.
