It is not used in the formula but given as an example.

Exactly.
> 2. Why is lastvalue(highest(high)) used instead of just highest(high)?
The trick is that highest(high) gives signals on EVERY new high throughout
all the bars loaded.
For example highestbars( high ) == 0 statement gives TRUE every time a new
high is reached.
LastValue( highest( high ) ) gives only ONE all-time high.
