Isabelle/HOL refers to higher-order logic as it is implemented within
Isabelle's logical framework.
Isabelle/Isar is a textbook-style syntax for proofs on the

Both: the reference manual (invoke with "isabelle doc isar-ref" from the
command line) lists the former as "outer syntax" and the latter as
"inner syntax". Terms are given in the "inner syntax", which depends on
the logic you are using, i.e. HOL in your case.

"isabelle doc prog-prove" is your friend.

I didn't have time to look into this, but indeed this is similar to the
example discussed in prog-prove. Note however that this is in the
"apply tactics" proof style, not using Isar.
