Actually Hand Solo's post is very accurate.
I can't beleive any airbus pilot wouldn't recognise immediately all the points he made.
Just be aware that much of the paragraph is taken up with the question of how to handle an approach where ATC hav eleft you high 30 to 50 miles out.
In my experience ( isn't it a pity we no longer get to sit on the jumpseats of other airlines) VS is a far better mode than Managed Descent when operating into busy TMA's. Certainly it's common at my employer (319,320,321) and I also watched Virgin pilots use it a great deal on their A340's.
