It's all about the
plant's ability to stockpile reserves of food and fuel. A seedling that is that prolific is likely better able to do so than it's siblings, but that is in
those particular conditions. Change those conditions and it may-, or may not repeat that, and other plants might even do better.
As mentioned in the linked article above, there are chemical processes that build stores and those that use them. Under certain conditions, the former beat out the latter and the plant can "think about sex". Under conditions that don't strongly favor the former, survival is more important.
I have a friend in Costa Rica that held a bunch of phalaenopsis >80°F for a couple of years. They grew beautifully, reaching 10-12 pairs of huge leaves each, but not a hint of blooming. After spending a few weeks at about 65°-70° to initiate spiking, they had built up enough reserves that each threw over a dozen spikes.
