Yes, the info is correct. However, the middle mouse button is on the button behind it and not on the scroll wheel directly. (See picture 3 on Digitec for example).

Quote:

Those who are used to using the mouse wheel as the middle mouse button have to get used to the Logitech MX Anywhere 2: Pressing the mouse wheel only switches between the two scroll modes. But Logitech has placed another button behind the wheel that can take over the role of the middle click. If you don't want to do this, you can also assign another function to the additional button, like all the other buttons on the mouse - for example, mouse gestures. By pressing the button and moving the mouse, various functions can then be carried out, such as switching between programmes or zooming in on the current view. This is not quite as intuitive as the gestures on a laptop trackpad, but anyone who works a lot on the screen can save a lot of time and work more effectively with such gestures.
