Preset Filter buttons - how does it work

[some]

Hi, in this video the guy shows how to add preset filter buttons (1M, 3M, 6M, YTD) etc:

For this he creates a measure that returns 1 or 0 based on the selected button and the difference from the current date and the max date in the data.

The measure is added to the chart as filter.

But how does it work? It only returns 1 or 0 - how does Power BI now which date row gets a 1 and which a 0. 

here is also the pibx file:

I feel like there is a step missing but I don't find anything in his file or so. 

Thanks

@some , I think you can create measures and use field parameters too.

Can you please share what you are trying to achieve?

Hi @amitchandak thank you for your answer. Your blog article comes close to what I want.
I want to show buttons with Months (January, February etc) and on click use a preset date filter for all visuals on the page. Is that possible?
