OK and why does this bother you?
Hard to say without being able to actually see what you did.
It could be Lightroom is both importing photos from the camera card AND creating previews. And it could be a whole lot of other things.
If you move your mouse up to the upper left of the screen where the two progress bars are showing the processes, and click, you'll get a larger drop down showing the details about the process and its status (i.e. "Building Previews - 67 of 247").
I typically have several processes going at once, because I set the option to have LR build Smart Previews, and I have my import to "Copy as DNG." So, after the import process, I get "Converting to DNG," "Building Previews" and "Building Smart Previews" all at the same time.
Thank you all!
