We recently showed that all five KEK and J-PARC uniquely assigned two-body $\Xi^-$+${ ^A}$Z$\to{ _{ \Lambda}^{ A'}}$Z'+${ _{ \Lambda}^{ A''}}$Z'' capture events in CNO light emulsion nuclei are consistent with Coulomb-assisted $1p_{ \Xi^-}$ nuclear states in a $\Xi$-nuclear potential of nuclear-matter depth $V_{ \Xi}\gtrsim 20$ MeV [1]. Here we argue that the recently reported $^{ 14}$N capture events named KINKA and IRRAWADDY are more likely $1p_{ \Xi^0}$--$^{ 14}$C nuclear states [2] than $1s_{ \Xi^-}$--$^{ 14}$N states, the latter assignment implying considerably smaller values of $V_{ \Xi}$.
