I found the following is mostly targeted at experienced users.

"The elements of a list, vector or record are not copied; they are
shared with the original."
 
Adding additional wording that it means that not everything is actually copied. 
Some aspects are actually reference values.  Meaning that if you change the
copied sequence, you could inadvertently change the original sequence.
