The [-1.9em] after each \\ is saying to move the next line up by 1.9em units. The number of em units depends on the font size: if we didn't have \Huge, -1.9em would move it to far. For instance, here we have the same code but the text is \normalsize, the default

The light blue line moved way past the lavender, and the salmon line moved way past the light blue! I moved the letters just enough for then to end up on the same line and looked overlayed. The "bottom" line will always be on top when lines overlap.

The last component of this code are the manually added spaces, which are also explained in the Intro to Stacking & Layering article. I put some spaces on the right of the lavender line using separated \s to shift it left, and some on the left of the salmon line to shift it right. The blue line remains centered. Notice that the closer together version has less spaces than the further apart version!
