If I recall right, you lift the arm up off the windshield with one hand, and hold it up while pulling the locking tab out. When the tab is out as far as it will go, you'll find you can release the wiper arm and it won't go back down. At this point some gentle wiggling or pulling on the arm in various directions will eventually work it off its splined shaft.
Having said all that, I think the shaft is indexed so that the wiper arm only goes on in one position; you don't get to reattach it one notch further to the right, or something like that. If the wipers are not parking properly, the problem is in either the motor or the linkage, not in the position of the wiper arm on its shaft.
