A lot of the comments are making the assumption that the buttons are telling the truth about being different sizes, but I’ve flushed plenty of toilets where both buttons do a full flush. If you can’t tell the difference after experimenting, it might just be broken or cheap tat.
The way these flush mechanisms work is adjustable. It’s entirely possible that someone adjusted them to have both have similar volumes for whatever reason

Actually, after using the toilet, only the big button works, the smaller one does nothing and both doesn’t change anything.
