They are using criticality in the same sense it used in physics (in the context of phase transitions). You may find the wiki article useful in this regard [1]

  This is a link which offers criticality as a metaphor with multiple meanings. You suggest phase transition criticality is close to what they mean, characteristic boundaries where matter transitions between solid-liquid, liquid-gas etc? I won’t spin mental cycles guessing. I’d rather the authors were explicit.

    Well frankly I did not read the article. But I am all too familiar with discussions of criticality in the context of neuroscience and it is always meant in the same way physicists use the word. I'm afraid this may be a scenario where some deeper knowledge is needed to fully appreciate the discussion. You would be well rewarded for putting in the effort though, it's a fascinating notion. I'd recommend starting with the Ising model [0] which is the canonical system exhibiting critical phenomenon.

The examples that wiki article lists aren't metaphorical, they're all essentially 'corollaries' (in a very loose sense) of the same underlying thing. Start with the Ising model.
