>I hope someone can find a reason why for instance ping4 fails and ping3 does not.

ping3 does not fail because you have '|| echo default gateway' on the
end, and this is the branch that is being taken. echo(1) returns true so
you get a status of zero from the whole list.

ping4 does not have an '|| cmd' branch, so the whole list retuns false
(non-zero).

These results are consistent with one of the pingtest commands returning
OK (or not returning NOK, technically)

I think you are looking in the wrong place.
