I can't play the piano, but I can mentally play back Flight of the Bumblebee in my head. The skill to produce and the skill to recall are different.

You could (or at least I could with little musical training) fumble around finding the right notes, and with enough time, eventually transcribe the song to sheet music though. mostly accurately.

just because you have no skill in shading and drawing lines doesnt mean that you shouldn't be able to replicate the correct proportions and details in the features of someones face.
