It is totally up to you how many ActionItems you want to show on the bar and how many you want to relegate to the overflow.
Generally the rule should be frequent user actions should be on the bar, infrequent ones in the overflow.
However you do not really have control over this, stating that an ActionItem is to be placed on the bar is a suggestion to the OS not a definate!
Different screen sizes and orientation will change how it looks and how many are placed on the bar.
