I'm sure, it's only a typo.
The programmers reference often is much less exact than the specifications.
Here the quote from the specs:
Except for differences in declaration and invocation syntax, virtual,
sealed, override, and abstract accessors behave exactly like virtual,
sealed, override and abstract methods.

The microsoft page http://msdn2.microsoft.com/en-us/library/9fkccyh4.aspx
states:
Remarks (nr 4)
Virtual properties behave like abstract methods, except for the
differences in declaration and invocation syntax.
Why is it "abstract methods", not "virtual methods" ?
