That's perfectly fine in my opinion. Since fermentation has really slowed down at that point, less flavor is just going to get burnt out by the yeast as opposed to adding fruit to the primary.
I just added a bag of Ocean Spray Craisins and a can of cranberry concentrate to a cider at secondary and it smells and looks great.
Primary: blueberry apple cider
Secondary: panty dropper cranberry apple cider
bottled: I should probably get some of those...
on deck: future brews suspended for the moment :(...
