If there is a single selected brush then it makes that brush selected in the combo so that the user can draw with it straight away rather than having to select it in the combo themselves. Note that it is not undoable because a) it makes no change to anything in the document and b) it can only be called whilst in the Freehand tool (and what would happen if it were undone outside of the Freehand tool is rather hard to define).
