Not wanting to downplay "how strong dancers are", because they obviously are, especially in their core, but I would imagine that most of the problems with these robots, and Atlas in particular, come from an entirely different weight distribution, rather than strength.
IOW, to achieve the similarly appearing moves, these robots have got to have a lot more strength to achieve the balance that comes naturally to most dancers: also why you rarely get 7ft/2.1m tall dancers doing the ballet/gymnastics style stuff — their weight distribution and "levers" (limb length) are so much different, making many of those moves doubly or three times as hard.
And focusing on their strength in the quotes in the article also downplays dancers' exquisite motor reaction time to reestablish balance (kudo to our brains is what I am saying).
