Looks like it is.  From the option's doc string:

  If non-nil, show parens when point is in the line’s periphery.
  The periphery is at the beginning or end of a line or in any
  whitespace there.

What you describe seems to fit the "any whitespace there" part.

maybe this text is confusing in some way?  What did you expect to see
as the effect of this option?

Thanks.
