I suspect they won't increase upload speeds till the network as a whole can sustain 64QAM.

The CMTS allocates minislots across both upstreams to a single CPE so it just means that there are fewer minislots available on one channel than the other and that the total upstream bandwidth available to that load balancing group drops from c.54Mb to c.45Mb.
Doesn't restrict to the smallest channel.
A modem requests upstream bandwidth the CMTS will tell it to use a frequency for b minislots at c time and d frequency for e minislots at f time depending on availability of slots on however many channels are in the bonded group.
EDIT: Have a look at
https://www.comhem.se/bredband/abonnemang - they sell 50Mb upstream speeds which would be impossible if there were a restriction to the highest bandwidth available on a single channel. The 30Mb-50Mb part covers their backsides in case of congestion.
