RFC said

http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.6

The URI in a POST request identifies the resource that will handle the enclosed entity. That resource might be a data-accepting process, a gateway to some other protocol, or a separate entity that accepts annotations. In contrast, the URI in a PUT request identifies the entity enclosed with the request -- the user agent knows what URI is intended and the server MUST NOT attempt to apply the request to some other resource.

So PUT request represent a single resource.
But multiparts means multiple resources in a single body.

http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html

In the case of multiple part messages, in which one or more different sets of data are combined in a single body, a "multipart" Content-Type field must appear in the entity's header. The body must then contain one or more "body parts," each preceded by an encapsulation boundary, and the last one followed by a closing boundary.

Therefore by semantic of PUT request doesn't match with multipart data. And the POST is matched because requested URI of POST request is "handler of enclosed entities".
