He got that message and I bet he got the perks, too. There is no message that says "you had 214 perks in fighters and now have 239," so without knowing what his total was he won't know that more have been added. If he waited to look until after the perks were awarded, then he sees the perks total and will not receive more for winning the war. There is no message that says "look at your perk count because we are about to add perks."
And just to be clear, you can earn more perks by playing than you can by winning the war. If you depend on the 25 perk award (each category) then you are doing something wrong.
