The soil will only go anaerobic if its standing in water, which as it's going dormant, it probably isn't, so should be OK.
As MikeB says they will stand a very broad mix of substrates, I grow them in pure live Sphagnum, peat/perlite mixes from 40-60 to 1, pure peat and peat and pine bark, and they all do well.
They do not like the soil compacted hard though, as that stops oxygen from the air and top watering to the roots, and do appreciate a repotting once the soil gets 'tired'. the time for which will vary on pot size, or bog size, and general conditions.
