The threat cited in the article said not just that the code would remain deleted, but that it would be "leaked" - presumably many of these were private repos.
You could never trust that the attacker actually deleted their copy of the repo, but then, the whole cryptolocking business model falls down if the attacker isn't at least moderately honest, so I can see why people would respond to that threat.
