Yes, this is the standard behavior.

No, you are misunderstanding. EXTENDED storage *allows* Postgres to
move large field values out to a secondary table. If a particular entry
is not large, then it won't be moved out.
Choosing one of the other storage options restricts Postgres from moving
data out, which can make things faster but also exposes you to a risk of
"row too large" errors. So I'd not recommend doing it unless you are
quite sure you know what you're doing and what your data will look like.
