Fields added using a ruby filter doesn't survive split filter

Elastic Stack Logstash
1

I have a logstash config looking roughly like below:

#ruby <1>
   ruby {  code => "event['@metadata']['scheduledTime'] = Time.now"     }
...
    split {
      field => "xxx"
      target => "yyy"
    }
...
#ruby <2>
   ruby {  code => " #read event['@metadata']['scheduledTime'] and do some calculation "    }

Field added in ruby <1> are not carried to ruby<2>. Split filter cloning somehow doesn't carry these fields onward.
The same ruby filters without split between works fine.

Is there a different way to add fields in a ruby filter or is the issue is from split filter?

Ok. Now I understand the issue.
