That is all correct. I do believe, though, that the 1L slide did inflate, but due to the bank angle of the fuselage and the ~20 knot crosswind it curled underneath. The jumpseater thought it was uninflated and mistakenly pulled the disconnect lanyard instead.
As to saving the bags... there was only one window up front that was usable, and there were 6 or 7 people aboard... it takes time to go down the strap, so a line formed waiting to go. The guys at the end of the line were just standing there so they threw the baggage out the open door. I'm not sure what else they were supposed to be doing.....
