I guess you'll have to ask them.
My opinion is that sanitizing the thermometer — especially before returning it to the holder (to avoid contaminating the wall mounted holder) and sanitizing it again after removing it from the holder — is good practice.
I don't need so-called 'experts' to confirm that.
