I remember Scott Duncan saying something along the lines of (not a direct quote): The 'person' on the court order/charge sheet is not the same 'person' on the BC etc...
By extrapolation, my interpretation is that the 'person' on the drivers licence is not the same 'person' as that on the BC, or passport, or SIN as they have all been created for different purposes, even though they have been derived from the same foundational document.
Of course I could be wrong and/or talking out my arse
