It is a case of confusingly written tables. The DSD line in the first table is NATIVE only. It doesn’t say it but it is. Mac does not do native DSD, they have to rely on DoP. DoP is based on the PCM rate limit, in which case it is 384 (from that same table), so can only carry DSD128 via DoP. That is it.
The second table is just stating the USB-B can carry either signal.
