This is an excellent circuit, The Diodes seem to cater for the peak of the 120 Volt supply and 600 Volts is being extra safe. The capacitor C! at 7:42 is shown as an electrolytic but this C1 has to accept both polarities. A good idea and it provides a great improvement to the unit.
Now to answer your question in seriousness, no it does not. You can put it at the "top", as shown at 3:57 (conected to the resistors R2, R4 and R3), or at the "bottom" (connected to D2, C1 and D4). It also does not matter whether the top AC terminal is live and bottom is neutral or vice versa, since the input is (typically) just a symmetrical sinusoidal AC wave.

Excelente, saludos from México
Where can I see the final schema?
Also can it be adopted for 230V mains?
Howdy.
Absolutely great.
Regards.
Thanks for you
But what about with 240Vac input
Which threshold-value does D5 have?
Although not explicitly indicated with a + sign, the capacitor symbol shown is typical of a polarized capacitor.
Which circuit can be used for 240v?
Electrolytic cap charged to -20v ? On your pcb can't see the c1 (electrolytic one)
Does it matter where you put the load?
It sure does, just ask your dad

These regulators need a noise suppression circuit
