There is a comparision between SL and BD models but from what I understand from the previos pages, SL is like a addition to BD pattern.That is we can use either BD and SL or just BD.
So from the comparison on page 728, is it implied that SL alone can be used without BD?
is it implied that SL alone can be used without BD?

I understand that but how can we compare SL and BD? They have different functionality and operate at a different level. From what I understand SL and BD are not patterns by itself but just a part of pattern which have a specific functionality ie add a level of abstraction in a pattern. That is the reason the comparision table didn't make sense to me.
