i think ebays thinking on this is that it takes a lot of negative experiences before a seller packs up his shop and leaves ebay

however its ebays belief 1 negative experience and most buyers leave and dont come back

so keeping the non payment strikes private removes any chance of them being negative experiences until they pass the 2 in 12 months.

be nice if sellers got the same treatment, 2 negatives in 12 months but not seen until you get 3
