This shows the name of the group the pico instance is assigned to. For each pico instance, they will be assigned to a default group for that particular pico instance. For example, a Platform will be assigned to the Platforms group and any Desktops will be assigned to the Desktops group.

For any EC's that are not assigned to an EC Group, they will be assigned into the Execution Contexts group by default. For more details about EC group and what it is used for, you can see EC Groups(3.0).
