Perhaps, but clearly not as severely -- at least not in my car ('90 535i).
For example, mine rises slowly to the mid-dial position -- it doesn't jump there quickly -- and it moves around a bit with load, outside temp, etc., [a very LITTLE bit, admittedly, but it does move]. Also, when I was having cooling problems a few months back, the gauge wandered all around the mid position with the rise and fall of the engine temp.
It seems from Jim's discription of the E39 gauge that it is essentially a three mode instrument: a moving gauge when it's really cold or really hot, and a fixed mid-point indicatior the rest of the time (which tells you little more about your temp than an idiot light would).
