The first graphic depicts the trajectory of an object climbing outward bound. It is not significant, but I have approximated the "35 mile" offshore "launch point" distance estimated by the SeeBS camera crew. Notice on the right that, when viewed from a point directly east of the trajectory, it appears to be purely vertical in direction.
In particular, notice that, when viewed from the north the trajectory is to the RIGHT.
In this second graphic, I depict the trajectory of an inward (eastward) -bound object. As with the outbound case, when viewed from directly to the east, its trajectory appears to be purely vertical.
BUT, when viewed from the north its trajectory is to the LEFT.

That illustrates perfectly why Gil Leyvas' video shows a plume veering to the right. It was an outbound missile.

The Leyvas video was taken to the south of the event. If you take about 30 seconds to analyze TXnMA's graphics, you will see that the picture you posted supports the fact that the track is inbound.
The viewpoint on that photo was well to the south of the contrail; It corresponds to the right side of my final diagram.
I deal with ALL of the data. You can't "cherry-pick" your way out of this one.
