I like this. The former has several problems anyway: you have to repeat properties if they can hold between several classes [3] and you have to draw lines connecting lines for expressing sub-properties or inverse properties [4] which looks rather confusing and is not supported by many visual modelling tools. [3] also shows a combination of the two problems: if you draw several lines for one property, you have to connect sub-properties to each of them or to an arbitrarily selected one. 
The only downside I see here is that adding ellipses for properties makes the diagram a bit more bloated.
