Could be, if you don't name things accordingly. If you ever do aerospace work you'll be blown away by the sheer amount of datums (points/axis/planes) required. Everything has to be properly defined and named. And for anyone that thinks this is overkill... each plane you create can be moved and/or rotated however you want. This might not always be necessary but when it is you'll be glad you did it. It only takes two clicks to create a plane.
