At the monent the green flag is only shown for the latter.
The intention of the rule change is to remove the discrepency between Q5.1.2 which states a Green flag is to be shown "during each formation lap" and Q15.1 (i) which states a Green flag is to be shown "during the formation lap".
All the change does is to make it "each". It clarifies the situation where there are for example 2 green flag laps before a race due to change of conditions from practice/qualifying - the green should be for both laps and not just the first (currently depending on which reg you read it could be either).
As you say, sometimes cars go from assembly / pits around the circuit to the grid and then have the "green flag lap" from grid to grid followed by race start - the first of these is not the formation lap IMO but is purely cars to grid and so doesn't need the GF, the second is and does.
