Adding up Options 2 and 3?

The credit language here says "For credit achievement calculation, the value of individual products compliant with either option 2 or 3 can be combined to reach the 25% threshold but products compliant with both option 2 and 3 may only be counted once." Not the clearest language, but it suggests that if you have enough products to meet, say, 20% of Option 2 and 5% of Option 3 you could get one point (as long as any specific product is only counted once). That would basically mean then that you have a pool of both options and get 1 point for 25% and 2 points for 50%. Is that right?
