I was only too young (say about 4-5 years old) to even remember that bulletin.
Was that a weeknight or weekend bulletin? I reckon if it was a weekend bulletin, it may have been launched to counter the Ten Weekend News. Either way it wasn’t until 2015 that Seven would again venture into having a national bulletin at 5:00pm on a Saturday or Sunday (Nine had already launched such a bulletin in 2011, after Ten’s 5:00pm weekend news briefly disappeared from schedule).
