This has little if any meaning. The power draw of the drivers varies widely
from idle to full acceleration. You can't practically match "impedances"
if the load has no fixed impedance. If you tried, the DC supply voltage
would be varying from dangerous to the Gecko down to nearly nothing.

Yes, the capacitors are there, specifically to give a low instantaneous
impedance to the drives. That's what a filter does, in this case.
