Toilets in skyscrapers are usually arranged in clusters near the core of the building (where the escape stairs, lifts, mechanical plants, service risers, etc. are) and are "stacked" vertically. This way, they can have a suitable number of soilpipes all located in one riser duct that travel vertically in a straight a line as possible. the wastepipes from individual toilets (and individual sanitary fittings) would discharge into the soilpipes via a network of wastepipes on each floor.
Having the soilpipes drop down in a straight line reduces the risk of blockage and subsequent leaking.
Think of it as a tree of pipes. The soilpipes are the largest and they go down vertically, much like the trunk of the tree. The main wastepipes carry waste water from the toilets to the soilpipe, they branch out from the trunk like the main branches of a tree. Smaller wastepipes carry waste water from individual sanitary fittings to the main wastepipes. Traps are fitted to the ends of these pipes at the joint to the fitting to stop foul smells from going back into the toilets (rooms).
Some tall buildings have more than one core, but the principle is still the same - cluster the toilets and stack them vertically within the individual cores.

They have several soil stacks grouped for the locations of the toilet facilities in the building. These travel down, but usually do have some bends (not s-bends, that would be a trap which is built into the toilet or installed under a sink) to slow the run of the sewage down to the main building drain.

S bends are traps, and thus prevent smells from returning up the lav. All of the toilet pans would therefore have a trap. Depending on the building layout, the pipework after each trap would tee up, eventually into one or more large risers which would drop vertically to the basement of the building.

One downpipe, the crap hits the bottom with such force it disintegrates and it becomes very easy to pump through the sewage system.

It would be a network of downpipes, staging the descent of the black water.
