If you look to the generated LaTeX code, you should see that there is
a both a "columns" and a "column" environment even though you only
specify BMCOL.

Of course not. AFAIR, there is no width attribute for "columns" in
Beamer. B_columns is meant to be used in addition to BMCOL, when options
the latter provides are not enough.

Only if you don't use it along with other environment. Otherwise, the
properties apply to the other environment.
