I confess that this would have been my ad-hoc recollection, too -- but
looking at the source code and wiki I find that's neither how I
implemented it nor how it has been documented (quoting from
http://wiki.povray.org/content/Reference:Finish):

"Setting finish-level fresnel will automatically activate (if set to a
non-zero value) or deactivate (if set to zero) the reflection-level
fresnel parameter. This can be overridden by specifying the reflection
parameters after the finish-level fresnel parameter. [...]"

This is consistent with the implementation.
