If you have a PC running the log in automation (lets say in your racks room), it will be refreshing the view everytime it does a segue, so when you come in in the morning it will be showing you the currently playing item.
If you then walk into the studio (where you have another copy of Myriad), that will still show the position in the log of where it was left last night, if you press "home" on the log it will take you to the currently playing item on the Auto PC.
Your Programme Controller has another copy of Myriad on his desk, he has the user rights to change the items in the current hour, he adds a few things in. If you look at the automation PC these will show up once it segues into the next item (refreshing the view). In your studio, you'll need to scroll up or down the log or press the "home", refreshing the view to see them, this is becuase your PC in the studio is not playing the log, and therefore not automatically updating the screen every segue.
Hope this helps.
