I suspect a lot of the confusion regarding how 6.4 is delivered comes from imprecise use of the word "upgrade." The components of the update (a.k.a. "the slices") are delivered via satellite download. However, unless you have access to the internal database of the TiVo software there is no way for you to known they are in place. Once they are, then a phone call is required to invoke a script that installs the new software onto the current alternate boot partition, swaps the boot partitions in the boot configuration, and then schedules a restart (which when the "upgrade" actually happens). It is the second part of this two stage process that has been problematic for many, since the DirecTIVos were failing to negotiate a connection to the TiVo servers. So again, unless you had access to the Linux command prompt on the TiVo, the fact that the software may be on your drive is irrelevant since you couldn't do anything with it.
Bottom line, the software code downloads via satellite, but the install process is executed during a phone call. Which is the "upgrade" - the download or the install? Most users would, I suspect, answer the install. So the "upgrade" does happen during the call, just using software downloaded via satellite.
This is further complicated by some users apparently not getting the satelliete download, for whatever reason, without which a phone call will do no good.
