Actually It appears not to be so:
In the very fresh
http://tools.ietf.org/html/draft-ietf-dime-diameter-api-02 you find:

"
3.4.4.1.  AAADictionaryEntryFromAVPCode()

  This function looks up a dictionary entry using a command code and a
  vendor id:

        AAAReturnCode
        AAADictionaryEntryFromAVPCode(AAA_AVPCode avpCode,
                                      AAAVendorId vendorId,
                                      AAADictionaryEntry *entry);
"

Has no reference whatsoever to an applicationId of any sort, that
would made the world flat (and the code much simpler :-).

Infact  http://tools.ietf.org/html/rfc3588#section-11.1.1
States that:
"
There are
  multiple namespaces.  Vendors can have their own AVP Codes namespace
  which will be identified by their Vendor-ID (also known as
  Enterprise-Number) and they control the assignments of their vendor-
  specific AVP codes within their own namespace.
"
Which implicitly says that is AVP-code and vendor-id alone to uniquely
identify an AVP. Why the F one has to infer this from a statement in
the "IANA Considerations" section of the RFC is open for discussion.

Are there really any cases where AVPs have the same code and the same
vendor ID but different meanings under different application IDs?

There are plenty of places in the 3GPP specs where an AVP defined in
one interface/application id is used in another one.  Would you only
use the app id to disambiguate?
