The instrumentation and collection *states* are handled completely
independently.

However, the instrumentation state of course influences the result.
If no simulation is not done, no events are triggered which could be
collected.

The default for the collection state is "on". Thus, in your scenario,
after the macro, events will be collected.

Hmm. Probably it's worth to put this into the manual.
