I'm not an exercise physiologist, but I'd like to look at this article in a different light.
1) The physiological testing occured after the 10th week. As such the group who just completed aerobic training will have better results as the other group has detrained aerobically for 5 weeks. In other words, the very design of the study is flawed towards a predisposed outcome.
2) The study with 3 groups (high reps, low reps, and no reps) found no difference in the groups. It's my understanding that in the first five weeks of a training program, "strength" gains are due to neurological adaptations to the specific motion pattern (may be wrong term, but the muscles are not getting stronger, you are just learning how to use them more efficiently). If these are varsity rowers than we must assume they are already performing at a high level of efficiency on an erg. As such, in my mind, you wouldn't see benefits for at least 8-10 weeks after real muscular adaptation has begun. Even then you still would not see benefits until the real adaptations are then expressed in the erg pattern. In other words, if your muscles get bigger then you must learn to use the bigger muscles in the rowing motion.
3) The article cites a similar study using elite athletes. I would reassert what I said in point 2, except note that elite athletes will be even more efficient in the rowing motion and would require an even longer time before any difference was seen. Moreover, the VO2max is unrelated to strength in the short term. Given a longer time to see real gains in strength with a training program that is appropriately balanced between MS, Power, and Endurance I would say there may be a difference.
Again, I'm not an exercise scientist, but I have to wonder about the use of these studies that have (to my eye) flaws in them. Moreover, the author notes further in the article that nearly every study did have issues that could readily explain the negative results. This does not raise any confidence in me. Ultimately, I think the only way to truly answer the question of the benefit of strength training in endurance sport would be a long term (ie: 1-3 year) study that tracks the progress of several groups against each other. From a scientific POV, I should think this would be very difficult to accomplish as there would be so many variables to account for.
My opinion, go ask some coaches who have been in the sport for 10+ years and have a reasonable rate of success. They have likely tried both ways and will have seen the effects of both over the long term. Sometimes experience trumps "science" due to the lack of funding/time restrictions.
EDIT: Added about 5 minutes after first post. I do recall reading studies that supported the notion that after a point, strength was of no further benefit to a rower (and that this notion exists in other sports too). In my mind this a more valid assertion and perhaps is something to investigate further in your readings. Try Nolte's book, the name escapes me ("Rowing Faster" I think) as I thought the results were in there.
