UMLR — meaning is not clear

In the part where the adornments on Association symbol are explained, the third bullet point seems to be confusing.

A property string may be placed near the Association symbol, but far enough from any end to not be confused with a property string on an end.

Though I am not in a position to say whether it's incorrect or not but I think it's bit convoluted as in "property string is placed so that it's not confused with a property string"?
