The amount of resistance created by the drogue and the design purpose of the drogue determine whether active steering is needed or not.
A speed reducing drogue, that is designed to just slow the boat, like the GaleRider, requires active steering to work properly. Among the other speed reducing drogues would be trailing warps, dragging your anchor and rode behind the boat, etc.
A Jordan Series Drogue is not a speed reducing drogue.
It produces far too much drag to work as one of those. It is a speed limiting drogue and essentially keeps the boat relatively still compared to the water surrounding it...with the boat making 1-2 knots generally. This type of device does not require active steering, since the boat is held stern to waves fairly solidly and fairly consistently. However, it does require that the drogue be properly sized for the boat.
As for a boat's tendency to head up...no, that isn't the case on most newer designs. If you read Don Jordan's paper on anchoring/mooring
and why modern boats tend to horse at anchor, you'd understand why this is the case.
How can a drogue not require active steering? She is still sailing down the wave- even at a slower speed wont she still want to head up? Would you locked the helm perfect mid-ship?

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
