Knowing a bit more anatomy than HUBS level, I think that's a clumsy sentence they've put there, and I personally wouldn't interpret it as saying "external iliac is right". The great saphenous vein joins the femoral vein, then the femoral vein becomes the external iliac vein, and to me that sentence means "note the point where the great saph + femoral becomes the external iliac".Refer to point 1. (This is the 2010 terms test 1 report)
[offtopic]Clumsy use of language in the first part of that sentence as well - "note on particular"...[/offtopic]
