It depends on the car, the rep may have been slightly confused.
Early X5s will cope with a bit of a difference front/rear no problem as they have a planetary centre differential. xDrive models might be more fussy due to the clutch arrangement.
The Mazda6 that my wife used to drive started juddering like crazy when we fitted two new tyres. I took the new tyres off and fitted some part-worns of the same make/model/size as the other two on the car and it was fine again. It was a horrible car though. We only bought it because I'd driven nothing but BMWs for years and felt we should be more open minded. I won't be making that mistake again ! She now has an E46
