Pico as SWD documentation

[microenh]

On page 21 of the 2024-05-02 version of Getting Started with Raspberry Pi Pico, under SWD Port wiring it says to connect GND(Pin 20) to SWD GND, GPIO24(Pin 18) to SWDIO and GPIO25(Pin 25) to SWCLK for SWD. This configuration works.

Right after that in the manual is a tip that says "When using the Pico as a debug probe, connect the GND, SWCLK and SWDIO pins on the debugging board to the matching pins on the board under test."

To me, this implies that a connecting the JST SWD headers on the two Pico's should work, but when I try this, while OpenOCD is able to connect to the debugger pico, it is not able to connect to the debug target pico.
