Does the camera revert to CDAF when back button AF is used?

Hey everyone,

I'm trying to get to grips with back button AF. I used it for years with my Nikons but since the switch to Fujifilm a few years ago i went back to using the shutter button to lock focus.

If i enable BB AF by setting the camera to MF mode and then set the AE-L button to initiate focus, will the camera revert to CDAF focusing?

Thanks in advance!
