A plausible scenario I can think of is:
PF “Go Around Flap”
PF moves THRLVR up one click.
PM “positive climb” (momentary, not sustained)
PF “gear up”
PM selects gear up.
No FMA Readout.
AC not in TOGA and keeps descending. Realised when still descending - just before pods hit. Selects TOGA.
It caught out an Australian airline some years ago, although without the ground contact.
EDIT - was distracted and took ages composing and have just seen others have same conclusion.
EDIT 2 - Have just heard audio of landing clearance read back with Continuous Repetitive Chime going off. It wasn't going off at the clearance for the approach. Whatever happened occurred between the two. Maybe there was gear problem that forced the go around.
