maybe he/she was assuming if you are going for heavy reservation you will be using 100% of hours? the other reserved instance pricing changes with hours

havent done a check to see if he was taking into account the discounted hourly price or just adding on on-demand hours...

Unfortunately, it's not an assumption. It's not immediately clear when looking at the pricing, but if you buy a heavy reserved instance you have to pay the 24/7/365 hourly rate. It's something for startups to consider as they look at their burn rate.
