But that and the reasons why Sony may choose to not do so aside, isn't the trick to really high sync speeds (north of 1/500s) to flash multiple short bursts with a dedicated flash that each light the traveling shutter slit (at high speed) and that in their accumulation give the effect of correctly exposing the full sensor with a really high shutter speed and flash?

it is, but HSS/FP offers much lower total light vesus just the one long flash impulse within x-sync timeframe with both shutter blades open to expose the whole sensor... so the camera can have both low spec x-sync (1/160) and HSS/FP at the same time... no contradictions...
