"Understanding" is a metaphor, used to describe an upper bound on model capability without excess verbiage. "Comprehending" includes the ability to appropriately manipulate the concepts when they're taken out of their ordinary framing context, which in principle a transformer model should be able to mimic a lot better than the systems we have; but in practice the training processes we're using do not teach the models to do this.
