I am afraid you did not understand the document above.
Miners are rewarded for:
- mining key blocks - this is the newly mined amount, that increases the total amount of tokens according to the inflation curve. Those are rewarded to whom mined the key block
- including transactions in micro blocks - those are the transaction’s fees that do not increase total amount of tokens. Those are split 40/60 between miners that mined the previous and the next key blocks
As you can see, miners have a strong incentive both to produce micro blocks and later to mine the next key block on top of the latest micro block. Those percentages are formaly proven to be a sweet point in the Bitcoin-NG paper.
