Why not? If the data is zeroed, there wouldn't be anything to find by forensics.

  From my reading it doesn't appear to zero the data, just overdrive the controller and hope to burn it out, which may or may not have downstream effects on the memory chip itself.

    That if it can produce enough current for it in the first place and I kinda doubt that. I've seen chips survive short term reverse polarity even, this might just be fine

  You're not zeroing the data, you're just burning up the flash memory in some way... which is not necessarily going to reliably damage the actual contents of the data, most likely it'll probably just damage some built-in voltage regulator or IO. For a truly determined adversary, you could pull the flash chip and read the contents directly. It's much more difficult, but theoretically possible if the information is valuable enough.
