I'm sorry but my understanding of the English language may be diminishing. That statement makes little sense if any. Whatever the topography does, finally it is the gusts of wind that cause the model to bounce around.
The Question was asked by a guy from Pakistan and I live in New Delhi India...we have miles and miles of flat uncontoured land and we have pretty gusty winds in the summers that really throw the models around - especially in crosswinds - and if it is a trainer with dihedral, the crosswinds tend to flip it over with more ferocity!!!

That is exactly what I was telling him to avoid at low altitude.....just be into the wind when flying low!!!!
