The past continuous is used to describe an action lasting for some time or serving as a background for other events.

In Scrabble we often use the past continuous and the past simple. The past continuous describes a background action or event in the past; the past simple describes a shorter action or event that happened for a longer action, or which interrupted it. The history provides a continuous history and provides explanation for the event.

So saying she was starting is simple used as a background.
