As the table value is on average much longer than 8 bits, one bit of input will affect nearly all output bits.

Others don't care, ignoring extra inputs and continuing to shift the same output bit.

Constant depth circuits that produce a single output bit.

The process is repeated until the desired number of output bits are produced.

That is, a total of 384 input bits are compressed together to 128 output bits.

That is, every output bit depends on every input bit.

Instead, one of the four output bits was used to select between the so-called A and B nodes.

The new output bit is the next input bit.

The mask is created by first removing all but the least significant bit (the output bit) of the current value.

Some only allow a single output bit.
