Very good video. Always interesting to hear someone competent talk about their area of expertise and experience.
To back up another step before we even get to the issue of steering, we should ask why any steering was necessary, even if the power went out? That is, the ship was running straight ahead directly between the pylons with the rudder presumably amidships when the power went out. I further suspect the rudder is basically "locked" into place when the hydraulic pumps are not actually running.
Given their incredible momentum, turning, slowing, and stopping huge ships like that are big tasks. I wouldn't be surprised if the stopping distance for such a ship would be half a mile or more and several minutes before you'd ever have to think about it drifting around in the current, which--given that it was in a river--would just be further towards the sea.
There are arguments about drift from current, wind, and the propeller fighting against current. They dropped anchor some distance away which as you said because of the momentum would in no way stop the vessel but it would make drifting worse. Besides losing power twice which shouldn't happen it's confusing why the ships bow can be seen move left, then right, then left again before hitting the pylon. Seems like it was intentional.
The remote piloting of a "ghost ship" to a fairly small target is probably not that easy, so that would explain the steering corrections. The power loss would then just be someone flicking the switch on and off to create the cover story. Then they had to erase part of the black box to destroy record of all the things the crew would never do and lack of actions they would certainly take.
And supposedly a harbor pilot was in control, so shouldn't we have heard all about him? You know, the standard rumors about how he was secretly gay and suicidal an a religious zealot? Nope, no discussion of him.
Maybe that's because there was no pilot on board, or anyone else.

This story is floating around out there, from a site most discount as fictional, and even the article itself admits the rumor has not been confirmed:
