The mixing is entirely optional.

There is little point, but the E24 range is available in 1% and 0.1% and
E96 in 1% also. I quickly checked digikey and found one line of 0.05%
resistor only available in E24 for example.
There is no reason to exclude combinations of E24 and E96 or even E192 if
you can get them with the same tolerance (and you can).
