Today your modem may be locked on at 579MHz but that could change anytime:
The DOCSIS spec (which defines the cable modem line protocol) states that communication frequencies between the provider's Cable Modem Termination System (CMTS) and your cable modem is 1) Variable and 2) In the range of 54MHz-1GHz.
If he puts in a 900MHz splitter and his cable co runs the data band higher than this then he has no Internet. If it works with that splitter today and the cable co decides to switch to a higher frequency tomorrow then his Internet drops. So if he is going to put in a splitter then its best to put in a higher frequency one and save the hassle of dealing with potential outages.
