They do. The B&M Luxos U has a built-in capacitor that holds the charge. The capacitor was added to regulate the voltage for the USB-charging function. But it also allows the light to hold on to a small charge when you pedal below the charging threshold. The Luxos U LEDs can provide some light even when you stop (at a low level and for a limited time).
However, the Luxos U has some other drawbacks, notably visual artifacts in the beam (due to the very-wide-angle reflector), and issues with the plastic housing (durability and possible water intrusion). The IQX followed after the Luxos U, but it doesn't have the USB-charging function (and therefore no capacitor).
