run-on-error="true", run this eca service even when the main service flow contains an error condition
ignore-error="true", do not allow an error return from this service to cause an error condition in the main service flow For example if you have a "validate" event eca with ignore-error="false" that when executed it returns an error, and you then you have an "invoke" event eca with run-on-error="false" then this eca will not be executed because an error condition exists.

The main service will never run if an error condition exists, I don't think that is something I would consider unexpected. I'm not really sure why the context validation is skipped but I don't think it matters much since the main service won't be run anyway. But anyway, just consider the main service to be set as run-on-error="false" permanently.
Aside from this there is the whole issue of transactions to consider, if a service error results in a transaction rollback then that will effect all other service calls executed within the same transaction.
