Ron, Tristan and others.

Might i only half seriously suggest that this is the lawyers at work. 
With that much fuel, I suspect they could have put the rocket perigee
below ground level in one go, thus causing a re-entry in half an orbit.
Such a procedure might be construed as delibrate and make the company
liable, after all delta 2nd stages have survived re-entry. Much is easier
to lower the perigee to 180Km and let the atmosphere randomize things,
changing it into an act of God!

lternatively perhaps they were testing out procedures for launching
other satellites. The argos launch put the secondary payloads (SUNSAT
+ ? ) into different orbit from ARGOS.
