But chlorophyll doesn’t absorb green, it absorbs other colors !

Blue and red are the maxima but chloropyll does absorb green light too - just less of it (and possibly less efficiently). The article claims "[plants] absorb only about 90% of the green photons." which seems to be a typo and should be absorb 10% or reflect 90%. I'm having great difficulty obtaining complete absorption spectra from the literature - nobody seems to have bothered investigating since the 1950s (https://sci-hub.se/https://pubs.acs.org/doi/10.1021/cr60147a...) with most modern papers seemingly content with declaring the red/blue maxima and not giving the full range.
The paper I linked shows nonzero absorption for greenish wavelengths approaching 10% towards yellow - which would marry with my interpretation of the article's typo.
