It might be simpler to think of these "numerous micro-satellites" as a single, larger satellite. They'll share the same orbit and speed. But they will, in my opinion, be less likely to cause a cascade. Any object they impact will likely be left intact and have less energy transfered to it than if the micro-sats were a single solitary object with the same mass. To answer your question: no. As the sibling poster and the article mentions, these micro-sats will only be in orbit for a few weeks. So there is no accumulation. The solution to space debris right now is avoidance for existing sats and decaying orbits for future satellites such as these.
