This issue has been covered at length here and I did not have to much difficulty in finding the answer using your heading as "search this forum" keywords.

A1 Simultaneous Zoom & Focus bombshell goes in to it in a lot of detail but basically the answer is that the XH-A1 and XH-G1 have one servo that does both functions. Your "manual" focus is not directly operating the lens remember, just triggering the servo.
