I suspect that the difference is in knowing versus unknowing use, and the deliberate choice of including learned elements or not on the part of the user. In the case of the ML model, it can reproduce a part of a training example perfectly, without the user knowing this happened (see the early Copilot analysis wherein it was possibly to get it to quote well known blocks of code verbatim). This is much less likely to happen when a user is consulting her own memories, though obviously never say "never".
