Indeed VM have operated like that for years prior to docsis 3 eg. using 1 US channel modems in service groups of 4 US channels.
A vmng300 modem wont automatically get less speed in 8 DS channel service groups, in fact its more likely to get higher speeds as there is more capacity available to all users.

Yet if one of the VMNG300's in each of the 4 DS channels take 120Mb then the other VMNG300 in your example can only achieve the remaining 80Mb. So only half the VMNG300's achieve full speed. i.e. two modems.
Compare that with 8 DS channels where 3 Superhubs can achieve the full 120Mb with a remaining 40Mb left over.
I'd say that's getting less speed.
If you mix VMNG300's into already saturated channels then the situation can be even worse where none of them achieve full speed.
