You are right it can't be simple multipath but it could be two entirely
different paths.
Or to put it more simply, a 1000km path difference equates to a delay of
3.3mS.
If the long path is 30000km and the short path 10000 km the difference is
20000km and the delay 67mS which is probably detectable.
