Alien 1979, deleted scene and the eggs

[grude]

There is a deleted scene on the Alien DVD where Ripley finds the still living crew members "cocooned" and in the process of being turned into facehugger eggs, Dallas begs her to burn them all with the flamethrower before it happens.

Assuming this had made it into the film was this supposed to be the origin of the eggs in the hold of the derelict? I always assumed it was clear by their placement and the laser alarm over them that they were cargo being hauled, instead of the crew of the derelict turned into eggs by the xenomorph that burst out of the famous pilot?
