The article is making a claim that can be summarized as...
the cognitive capacity to share with conspecifics something learned more than 120 seconds ago, is unique to humans and orangutans
They also inform you that bees have this capacity. That should be enough to make anyone skeptical. It seems like they identified a particular behavior unique among apes to Orangutans - suppressing vocalization in response to threat - ran an experiment to confirm their bias, and are spinning it as a story about the ability to talk about the past (rather than simply that Orangutans have evolved to deal with perceived threat by keeping quiet while the threat is present, and then going bananas after it's gone).
Conveying info about the past is something bees can do; yet it escapes Chimps and Bonobos. Yeah, ok.
