It means one event can trigger two or more tasks. And two or more events can trigger the same task. The way you do this is by using two or more channels.

This will assign your "Event 1" to PPI channel 0 and 1 and trigger two different tasks:

NRF_PPI->CH[0].EEP = "Event 1"
NRF_PPI->CH[1].EEP = "Event 1"

NRF_PPI->CH[0].TEP = "Task 1"
NRF_PPI->CH[1].TEP = "Task 2"

This will assign your "Event 1" and "Event 2" to PPI channel 0 and 1, and trigger the same task:

NRF_PPI->CH[0].EEP = "Event 1"
NRF_PPI->CH[1].EEP = "Event 2"

NRF_PPI->CH[0].TEP = "Task 1"
NRF_PPI->CH[1].TEP = "Task 1"
