What is the reason for using both layerids and layer_option_all in identifyparams?

In the identify sample, the code shows using both specific layerids and the option to use all. It seems like it should be one or the other.

identifyParams.layerIds = [0,2];
identifyParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_ALL;
