What does this mean?

I was looking at Google Trends and began to check out their trend comparison feature, in which you enter multiple search terms, separated by commas, and compare their trendiness.

Take a look at the data below, which compares the five terms baptist (dark blue), methodist (orange), lutheran (light blue), presbyterian (red), and episcopal (green).



It's interesting to note that searches on the keywords for these Protestant groups seem to move in a synchronized way.

I guess the visible church is more united than we thought.
