This is gibberish on a number of levels. It does not describe the behavior of social bees at any time during evolution or since creation. Bees visiting flowers do so to gather nectar and or pollen mostly for feeding to juveniles. Males social bees are not equipped to do that.
The article probably refers to the specialized solitary male bees which may pollinate certain species of orchids because they mistake part of the orchid flower as a female solitary bee of the same bee species. If the time of male bee sexual activity does not coincide with the blooming period of the orchid there may be a problem. However, none of that information seems to appear in the article.
I found another article that seems to be more accurate on the specific study:
“The work used museum records stretching back to 1848 to show that the early spider orchid and the miner bee on which it depends for reproduction have become increasingly out of sync as spring temperatures rise due to global warming.
The orchid resembles a female miner bee and exudes the same sex pheromone to seduce the male bee into “pseudocopulation” with the flower, an act which also achieves pollination. The orchids have evolved to flower at the same time as the bee emerges.”
