In addition to other posts, note that the point with Ola's script is not that he rebuilds things in a different way. It is still the same command as if you would do to this manually. He just packages it for you, so that it is easier to administrate.
I would guess that in this case, by default he skips tables with fewer than 1000 pages, and I guess there is a parameter to control this.
I would say that today there are many workloads that can do well without any index rebuild at all (as long as you still update stats!). Fragmentation matters little SSDs, and fragmentation has never mattered much in well-designed OLTP databases. At least not what is known as logical fragmentation. Page density is a different matter, but it is also more expensive to measure.
