I think he's referring to the fact that item 9 in that list is centered below the two columns.

It definitely has the look of something done on a classic PowerPoint template. You can see that it doesn't look like it was prepared to be a letter or something with the standard print margin limitations of Word; the background goes to the edges.

You can mock up something that looks like that in Word, but I can't quite see what the thing you snapshotted is. Is that a PDF, or a web page? You might try downloading the web page (right mouse click, SaveAs) and see if that background image comes by itself as a file.

If not, you'll use Insert Shape and put a rectangle over the top half, change the fill to something that looks like marble or crumpled paper (the standard fill textures I have in Word 365 aren't an exact match), then copy and paste the box and change the fill of the second box to the color blue that matches yours. From there, you might want to use text boxes for the various text portions. That way you can drag them around and not have to tab and space your way there.

I don't see that as a standard template in my Word or PowerPoint, but it might be a slightly older one. If you have PowerPoint, open and browse the templates. Also look at your (File/New) Word standard templates. I found a few for flyer backgrounds, but nothing that matches the business-like style that you show in the picture.
