Each of the Great Void Shifters had paths entangled with many others, and usually only the Werdlem Empire could settle those paths when travelling between Universes. The twins' group had no such problem, though. Using the system's capabilities, they could select a specific Universe from the hundreds available for that route.
They left A1 two days earlier, so they obviously already reached D198. From there, they travelled to the next Great Void Shifter Formation, a broken one whose Abyssal Path was connected to many other Universes, specifically F956.
So, by the time Jruse-Uh received the information about the A1 Shifter's available paths and sent people to check them on the other Universes, the twins' group was long gone.
