When you double-click, a word is selected, when you then shift-click, the
selection is extended from the word already selected to include the word
that you shift-clicked on.

Almost - the shift-click is a single click rather than a double-click ...
the system remembers that the last selection was by a double-click, and
extends by word.

Yes - that's how it works - the selection behavior is determined by the
original single/double/triple click, the later shift-click ignores the
count of new clicks.
ie if you did an initial triple-click, then hold down the shift key and
click elsewhere, the selection is extended by paragraph irrespective of the
number of times you now click.
