Can I apply split processor on more than one field?

What about this?

PUT _ingest/pipeline/split1
{
  "processors": [
    {
      "split": {
        "field": "q5",
        "separator": "[a-z][.] "
      }
    }, {
      "split": {
        "field": "q6",
        "separator": "[a-z][.] "
      }
    }
  ]
}
