follow orders = carry out instructions?

Context:

In a paper published in the July 1 issue of the journal Cell Cycle, Duesberg and UC Berkeley colleagues describe their theory that carcinogenesis – the generation of cancer – is just another form of speciation, the evolution of new species.

“Cancer is comparable to a bacterial level of complexity, but still autonomous, that is, it doesn’t depend on other cells for survival; it doesn’t follow orders like other cells in the body, and it can grow where, when and how it likes,” said Duesberg. “That’s what species are all about.”
