Only Boeing's document and the subsequent EAD made the connection between this behaviour and the "runaway trim" checklist. Which is why using the wording "existing checklist" by Boeing is disingenuous. It's a weasel-word trying to imply that the pilots should have used the checklist, although it was not applicable before now.

From the Synopsis (quoted above) of today's Interim Report, about the previous flight:

The PIC noticed the aircraft was automatically trimming AND. The PIC moved the STAB TRIM switches to CUT OUT and the SIC continued the flight with manual trim without auto-pilot until the end of the flight.
