What is the meaning of the term non-lagging (in relation to the indicator)?

 
Do you need one at all? If it is not lagging, then it will react to small price movements and will give a lot of false signals. Or does it mean that it does not react to these small movements, but does not lag when a significant movement starts? But is it possible?
 

And this is a vague term altogether.

How can an indicator be "lagging"? It is exactly like that when it is counted. The MA is not physically "lagging", it is showing the moving average on the bar it is calculated on, where is the "lag"?

All this was invented by those who need an excuse for their improper use of moving averages - they lost their deposits, and who is guilty? Well, of course, the "lagging indicator" is "too late" to show "accurate entries".

This may prove to be a lagging conclusion.

The lag, I think, should be calculated from the last extremum of the zigzag till the time of the signal appearing on the input which was given by the indicator.

The display of the next (ascending) trend line or continuation of the current (descending) trend line by the zigzag indicator will occur under certain conditions after some time. This is its lag.
 

Non-tardy, meaning either current or future, not past, not ex post facto.

not past, not ex post facto.

 
There may be some of the non-delayed stuff. This is divergence. No matter what you look at, with the right approach, it works.

But it's not essentially an indicator either.

For the zigzag to be fully visible, the "graph from above" option must be unchecked.

 
A "delayed" indicator is defined as a "signal" that is not given at the right time. A "signal" is a freely subjective description of some visual events and their interpretation.

The divergence is delayed. In order to identify it, the last extremum must form. And that is already a lag.

Second: when a divergence has been formed, the movement it predicts may be too small.
