And the likelihood of you having a property called Myclassfield1 is?
Most developers start a class name with a capital, and a property name
with a lowercase. So the likelihood if you are adhering to convention is
slim to squat. That said, I think they should have put in a -> or a :
character :)

It sounds like they've helped out by giving more data than was
necessary. This can be useful when working with the data to know it's
origin.
