Seems to be a bug to me. Can you file a JIRA on this?

> A minimal test case demonstrating this behavior can be found here:
> The javadoc for Get mentions 'Only Filter.filterKeyValue(KeyValue) is
> called AFTER all tests for ttl, column match, deletes and *max
> versions*have been run.'; for these two filters this behavior does not
