The stems come back really thick - ratty bottoms I assure you are there - but you don't see them.
Each pruning is done at a slightly greater height than the previous one - that way you're pruning the side shoots, not the exact stem you planted. After 3-4 of those types of prunings, you'll get a nice thick bunch. Eventually,
you'll need to really hack it back to 'start over'. Some stems bounce back from this easily (rotalas) - others, not so much (stellatas).
