They do and they don't ;-)
The Advanced CF course teaches the bits about structures and pointers with
reference to StructCopy(). However Duplicate() is much more generic than
StructCopy() i.e. can copy more than just structs, and (IIRC) performs a
deep copy.

Not entirely true. Structcopy does actually duplicate the structure in
question. I think there's some confusion here over <cfset
somenewvar=anoldstruct> which creates a pointer to the original. Structcopy
however only performs a shallow copy in that any embedded structures within
the structure that you are trying to duplicate aren't copied wholesale but
are referenced through pointers.

Using StrucyCopy you still reference the original structure. So, when using
structCopy of an application or session variable you still have a pointer to
the shared memory
