This number is used to generate the random distribution of the instances. If you use several Scatter extensions on the same object, make sure the seed number is different for all of them to produce a totally different random distribution and avoid several instances being placed in the same location.

overlaps
This option automatically removes the overlapped instances to ensure a distribution without collisions or overlaps.
...
Randomizes the orientation of each individual instance, specifying the range of possible rotation values as a percentage of the nominal Rotation parameter. For example if Rotation Y is set to 180º and Rotation Y Variation parameter is set to 50%, the orientation in Y of the generated instances will be randomized between 90º and 270º.

This percentage allows you to modify the direction of the Y-axis (up) of the scattered objects:
