When closing "Search Window", the editor jumps to another segment

I don't understand this new “feature”:

Example:

In the editor I have a multi-page text;

I press CTRL + "F" (Search Window is opening) and I’m searching for a word. The editor finds this on another page;

Now in the editor I scroll some pages down (PAG DOWN);

Now I close the "Search Window” (by clicking on CLOSE) and the editor jumps again to the segment where the searched word was last found.

Can someone tell me, what is this good for?

Thanks ;-)
