There is no contradiction. Table 9.3.A is a table to provide guidance for segregation. Even if substances require segregation per Table 9.3.A, they May not react dangerously as the example cases listed in 220.127.116.11(a), even if placed in the same kit. On the other hand, substances not listed on Table 9.3.A May react dangerously if accidentally mixed such as in the case of strong acids and strong alkali substances even though they both belong to Class 8 requiring no segregation. These must not be in the same kit. Such determination will require knowledge of chemistry. Personnel of the transport chain, i.e. cargo agents, forwarders and airlines, are not chemists and therefore not qualified to make such determination. The best is to rely upon the technical knowledge of the manufacturer or the shipper who have ample knowledge of the products they produce and export. The rule is that even if the substances fall under Table 9.3.A, if they do not react dangerously as explained in 18.104.22.168(a) they May be placed inside the same kit. In addition, even if the substances do not fall under Table 9.3.A, if the substances would react dangerously as listed in 22.214.171.124(a), they must not be placed inside the same kit.
