1.2 and 1.5 are just a convenient way of grouping several property
setting events into one music identifier like \cadenzaOn. You could
define
cadenzaOn = { \set ... \set ... }
also as
cadenzaOn = << \set ... \set ... >>
The difference is that in the second form, the time of the events runs
in parallel rather than in sequence, but since all events are
instantaneous, that does not cause different results.
