As per 5545, URL is meant to be a pointer to an alternative representation 
("more dynamic rendition") of the event - e.g., it could be a web page with 
details of the event. SOURCE, on the other hand, is meant to be a pointer 
to the original location where the iCalendar data itself was retrieved from.

I could add the following sentence to the SOURCE property description to 
help clarify the differences:

    Note that the URL property (Section 3.8.4.6 of [RFC5545]) defines a URL
    for an alternative representation of the calendar information (which
    could take the form of a web page, or an image, etc), whereas the
    SOURCE property is used to refer to the location where updated
    iCalendar data can be found.
