Scaling on consumption plan: inconsistent documentation

It is not clear to me how function apps scale that share the same consumption plan.
The documentation on this is inconsistent.

Excerpt from [Azure Functions Consumption plan hosting](https://docs.microsoft.com/en-us/azure/azure-functions/consumption-plan):

> Function apps in a given plan are all scaled together, so any issues with scaling can affect all apps in the plan.

Excerpt from [Event-driven scaling in Azure Functions](https://docs.microsoft.com/en-us/azure/azure-functions/event-driven-scaling):

> Function apps that share the same Consumption plan scale independently.

I was a bit surprised to read that all function apps in the same consumption plan scale together... that does not make sense to me. Can you confirm which of the above is in fact the correct one?
