Completely harmless and can be safely ignored.

Actually it means that the encoder wanted to make a scene change (i.e.
it knew here was a scene change) by closing a GOP and starting a new
one. It can only do that if the GOP that is going to be ended has
at least '-g' frames in it (default of 9).
Nothing at all to worry about. You can allow the encoder to use
shorter GOPs if you like with '-g' ('-G' sets the maximum).
