Are matlabs coordinate systems for the camera calibration work flow inconsistent or am I missing anything?

I used the stereoCameraCalibrator app to perform a stereo calibration. I gave the app the images of the left camera as camera 1 and the images of the right camera as camera 2.

I got this result for the position of camera 2:

stereoParams.TranslationOfCamera2
ans =
           
-171.5241267101          3.21275958152786          2.31278512483859

I would have assumed, that this vector is giving me the position of the second camera in world coordinates. But according to this link that would mean, that my second camera is left of the first camera which is definitely not the case (and I'm absolutely sure, I didn't mess up the images of the two cameras/folder paths). So why is the first value of the translation vector -171 and not +171?
