Yes, this was a deliberate move away from the no-duplication style
used in the professional documentation, for pedagogical reasons.

At each language level, I gathered in a separate section called
"Common Syntax" the forms that that level has in common with the
previous level. The idea is to make it possible to get a quick sense
of of the commonality between the levels, while giving the students
confidence that documentation page they are looking at is
comprehensive.
