Geometry object stuff

I have used this stuff before but this afternoon (because of my fading brain) I got stuck again.
This page says that using point geometry objects, you can access the X,Y,Z like this:

http://resources.arcgis.com/en/help/main/10.2/index.html#//002z0000001t000000

for row in arcpy.da.SearchCursor(infc, ["OID@", "SHAPE@"]):
# Print the current multipoint's ID
#
print("Feature {0}:".format(row[0]))

# For each point in the multipoint feature,
#  print the x,y coordinates
for pnt in row[1]:
print("{0}, {1}".format(pnt.X, pnt.Y))


If you do this, all you get is this :
>>> geom1
<PointGeometry object at 0x128e50d0[0x128e51c0]>
>>> geom1.type
u'point'
>>> geom1.X

Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
geom1.X
AttributeError: 'PointGeometry' object has no attribute 'X'
>>>


This had me stuck for about an hour until, from somewhere in my aging cortex, I remembered you had to do this :

>>> geom1.type
u'point'
>>> geom1.getPart().X
37.85577369550394
>>> geom1.getPart().Y
-5.721226269422574
>>> geom1.getPart().Z
633.8880000000063
>>>


Oh, and if you try to iterate over a geometry object like in the help, that fails as well.

>>> for p in geom1:
print p.getPart().X

Traceback (most recent call last):
File "<pyshell#10>", line 1, in <module>
for p in geom1:
TypeError: 'PointGeometry' object is not iterable
>>>


Dear esri, when is either the attributes of the geometry going to get fixed, or the help files when you want to actually do this stuff?

Thanks,
