Ok, maybe I've figured this out. Its possible that the non-obvious result that Jack O'Malley James came up with is as a combination of poor
journalism and not reading the article properly.
The original paper was presented at a meeting of the Royal Astronomical Society...
where it says...
The potential for hosting photosynthetic life on Earth-like planets within
binary/multiple star systems was evaluated by modelling levels of
photosynthetically active radiation
Combinations of M and G stars in: (i) close-binary systems... were explored.
Type M stars are the red dwarfs, and type G stars are like our sun.
Now the news article does mention "sunlike stars" in passing, but the emphasis at the end in the quote only mentioning red dwarf stars makes the
reader think that this is the important bit. But it isnt.
Looking at the comments places on other websites where this article has appeared, it seems that many others who read it was mislead as well.
Depending on how BOTH of the available spectrum to the plant is distributed, the plant gets a good dose of red, green and blue, and thus make it
worthwhile to get them all, and reflect none.
