They aren't, though. That is not the official ruleset. Later rounds do not count more than earlier ones, although this actually brings up a good idea. Later rounds SHOULD be more valuable than earlier ones, in order to have an official way to judge cardio and endurance. Doing well in later rounds should be more valuable than doing well in earlier rounds, both for 3 round fights and 5 round fights. However, this is not the rules, so Jones only won 2 rounds to Reyes' 3, and lost the fight. Sadly the judges scored it wrong (with one judge not watching and giving Jones 4 rounds!) and so Jones, like GSP, has a "win" on his record for a fight he actually lost, and his GOAT status is forever banned from legitimate conversation on the topic (although some would say the PED stuff already did this to Jones).
