Well, essentially yes. But it does take time and effort, and daily training during veg and the first 3 weeks or so of flower. Sometimes you have to you use twist ties to keep them in place. You let them grow through the screen a bit, and then tuck them under, let them grow up the next hole a bit, and tuck them back under, over and over until your screen is filled or they stop stretching. You can tell they are slowing down, and that's when I start letting them come through their final resting spot, and do some final placement of the slower ones. Then I wait about a week, while trimming and cutting leaves that are shading. By then they have kind of leveled off in their growth patterns and I then do the final trim underneath the screen. At this point, everything must go under there. No fans, no shoots, nothing but the stems you have trained. This is important for 2 reasons, air flow, and to allow the plant to concentrate on the buds instead of wasting energy on shoots that aren't going to develop.
Hope all that makes sense,
