How did you get 4 miles per 100 yen total in your initial sentence?
I calculate 3 points per 100 yen as you mention in your second sentence. 1 shopping mile and 2 add on miles with platinum amex.
When you purchase good/service/ticket from designated shop, or dine at a designated restaurant, you get 1 shopping miles and 1 additonal special retailer mile.
JAL online ticket/sales is one of those special retailer shop.
So,
1 shopping mile
1 special retailer mile
2 add on miles
In total, you get 4 miles per 100 yen.
JAL gold card gets 1 add on mile, so 3 miles in total per 100 yen.
