Quoting the manual

     Also, a headline with an =E2=80=98ignoreheading=E2=80=99 environment w=
ill have its
     contents only inserted in the output.  This special value is useful
     to have data between frames, or to properly close a =E2=80=98column=E2=
=80=99
     environment.

    [...]

       Moreover, headlines handle the =E2=80=98BEAMER_COL=E2=80=99 property=
.  Its value
    should be a decimal number representing the width of the column as a
    fraction of the total text width.  If the headline has no specific
    environment, its title will be ignored and its contents will fill the
    column created.

so there is no incentive to use "ignoreheading" in conjunction with
BEAMER_COL property.

Of course, if you see an improvement on the wording, suggestions are
welcome.
