Well, the article was talking about objects about the orbit
of Saturn, but even then they were talking about 10 years
under thrust followed by a 20 year transit time to Mars.
So your observation still applies.
The article did make a point that it is not necessary to
move the object into an elliptical orbit. One can move it
into an orbit that intersect the gravity well of a gas giant
so as to take advantage of a gravity assist maneuver.
Of course, by this time, there may well be other human colonies
