It was partly in response to the way you had your tasks expressed, partly because being able to connect the task to the project is usually the second question that gets asked, and yes, if it's not going to be obvious to ME what project I'm doing the action for, I'll put something in the item to tell me.
For example on my @Computer list right now I have
Update Conquer the World Schedule
Update Invade North Pole Schedule
Email Debbie requirements
Email John requirements
(OK, just kidding, those aren't the real project names)
Without the reference to the project I wouldn't be able to tell the Update Schedule actions apart. I didn't need to identify the project for the requirements because I know what it is based on the person I'm contacting.
Hope that helps.
