Remote UIDocument often appears from the cloud

I work with documents in the cloud ... * Add a document to the cloud * Delete this document from the cloud * Somehow this document appears in a few seconds.

Here are the details:

I am creating an instance of a UIDocument like this

    NSURL *ubiq = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];
    NSURL *ubiquitousPackage = [[ubiq URLByAppendingPathComponent:@"Documents"] URLByAppendingPathComponent:@"somenewfilename"];

    MyDoc* docTemp = [[MyDoc alloc] initWithFileURL:ubiquitousPackage];
    docTemp.mapContent = [NSString stringWithString:self.currentdocument.mapContent];

    [docTemp saveToURL:[docTemp fileURL] 
      forSaveOperation:UIDocumentSaveForCreating 
     completionHandler:^(BOOL success) {            
         if (success) {
             DLog(@"New document %@ saved/added: %@", newFilename, docTemp);
         }
         else {
             DLog(@"Failed saving new document: %@", newFilename);
         }
         [docTemp release];
     }];

Then delete it later as follows:

    NSURL* fileURL = self.currentdocument.fileURL;
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void)       {
    NSFileCoordinator* fileCoordinator = [[NSFileCoordinator alloc] initWithFilePresenter:nil];
    NSError* error = nil;
    [fileCoordinator coordinateWritingItemAtURL:fileURL options:NSFileCoordinatorWritingForDeleting error:&error byAccessor:^(NSURL* writingURL) {
        if (error != nil) {
            DLog(@"Error with %@! %@", fileURL, error);
            return;
        }
        DLog(@"Got writingURL: %@", writingURL);
        NSFileManager* fileManager = [[NSFileManager alloc] init];
        if ([fileManager removeItemAtURL:writingURL error:nil]) {
            DLog(@"Deleted %@!", writingURL);
        }
        else {
            DLog(@"ERROR Failed deleting %@!", self.currentdocument);
        }
        [fileManager release];
        [fileCoordinator release];
    }];
});

Now, despite the above, it seems that the file has been deleted for the (short) message, but in some cases the deleted document reappears in the cloud after a few seconds. (I can verify this through iCloud settings on another device or through a request that sends update notifications). Only in some cases does the file remain deleted. What's happening?
