During shaping periods, in theory, yes. If they didn't use more than that unshaped though people wouldn't notice much of a performance hit when using them during managed periods.
It's also been noted that the shaping seems as much use as a chocolate fireguard when people really try and hide what they're doing, which is why protocol agnostic solutions are the future and will be on a cable ISP near you in time.

P2P, etc, according to Sandvine will be as a minimum 65% of upstream traffic. There'll be some torrent traffic which wasn't identified due to obfuscation, some of the SSL will be NNTP, the Teredo will pretty much 100% be torrents.
59.68% torrents + 3.64% PPStream + 1.76% ED2K gives you 65% without even needing assumptions.
It's not a huge leap to imagine areas where an upstream is running at 50% 24x7 due to P2P or NNTP encapsulated in something else, this is a problem for cable companies throughout the world and one VM are addressing, however it's a more complicated process than the initial shaping deployment.
