If you were going to make a software, where you can see places though a webcam, would you call it Windows, even if it's a fitting name?
Tesseract goes by the name Tesseract, tesseract-ocr is just the name of the Google code project.

To be honest though, my view is very biased because I don't care about the ocr project at all. I'm sure it's a very nice project, but hardly a tesseract really.. =p
