It just acts fundamentally different than someone who would remember.
If someone only remembered vague scraps of what you'd expect them to remember, you might say the person can't remember.
It's much closer to notetaking and reviewing before responding than it is memory.
The issue with anthropomorphizing like this is that "memory" comes with baggage of expectations for it to do certain things, and it breaks them.
Just like "thinking" implies chain of thought, but you'll frequently get those reasoning traces and then a 180 in the final message.
