In raw words, a MOSFET is a switch controlled by the Gate signal, when you apply a low voltage to Gate pin, the electricity can flow between Drain and Source pins, this is used by the pico to generate the Glitch, making a shortcut on the capacitor(s) of the CPU.
That's why we need a MOSFET and no an ordinary transistor, for an instant almost 10 Amps can run between the cap needing thick conductors
And the need of precision of the timing require short wires between cap and MOSFET
