Multiple activities for the same session in Session Tracking Details report

Question

How can SU analytics in the Session Tracking Details report capture multiple activities in one session ID at the same time?

Answer:

1. The user has logged in from two different tabs using the same credentials and at the same time. This will create the same tracking requests at the backend and thus capture all session activities in the same session ID.
2. A very scant difference in time between two activities could be another reason for tracking multiple activities at the same time.
