So does "Update of OCR1x at" mean that only when when the pulse wave form has reached the value of BOTTOM (or the end of a period), that's when the value of OCR1x will be passed on to the OCx pins...
Yes, that's what it means. To prevent glitches in the PWM output, you frequently do NOT want the PWM waveform to change immediately the instant you ...

You should write ";" end of each lines.
analogWrite(11, 64);
delay(1000);
analogWrite(11, 0);
delay(1000);

No, you don't.
Resistors are used to limit and control current (amongst other things) and you don't need to do that when sending a signal from one digital device to another.

pinMode(3,OUTPUT);
Pin 3 on the Nano is OC2B. It's PWM is controlled by Timer 2. You
want to use pin 5 (OC0B), since you are using Timer 0. Or
switch to Timer 2.
Phase correct PWM with top as OCR0A
Note that this is the description of mode 5. If you want this mode, you
have to set both the bit WGM00 in TCCR0A (which you did)
and the bit WGM02 in TCCR0B (...

A servo motor doesn't just require a single pulse to send it to a specific angle. It requires a constant stream of pulses at the right frequency for it to track what the angle should be.
By sending one pulse you're just hinting where it might like to go to, then stopping. It's never going to get there, unless you keep sending those pulses fast enough.
