Think of it this way. The ISP has a connection to the Internet and must pay for that access by the amount transferred. They are counting your bytes at "their" connection to the internet. Every byte that comes from your modem and reaches to the Internet costs them money that they must charge you for.
But anything that originates and stays within their own network and does not go over the internet is not costing them anything so they have nothing to pass on to you for charges. As long as the content they are giving you has not come from the Internet in any way, they shouldn't count it towards your data cap. That would be charging you for Internet access you never used.
If they're just trying to cache Netflix or YouTube data, then that would be from the Internet and they should not be able to give you any special deals.
Of course, in reality, how they make your modem know the difference between the two types of traffic is beyond me. I'm fairly certain they get their byte count from the modem.
