OCMock: OCMPartialMock object calls the actual method rather than the stub

I have 2 methods in a class where one of them simply calls the other one with specific parameters. The methods are as below:

-(void)loadAllFollowersForUser:(NSUInteger)userID withResponseHandler:(_Nullable CompletionHandler)handler {
[self loadFollowersForUser:userID
                fromOffSet:0
                   toLimit:100000
       withResponseHandler:handler];
}

-(void)loadFollowersForUser:(NSUInteger)userID fromOffSet:(NSInteger)offset toLimit:(NSInteger)limit withResponseHandler:(_Nullable CompletionHandler)handler {
    NSLog(@"Actual loadFollowersForUser method got called!");
}

I am trying my hand on TDD and have been using OCMock. I have the following test that simply tests that loadAllFollowers is internally calling the other method

- (void)testLoadAllFollowersCallsLoadFollowers {
    id partialMockSUT = OCMPartialMock(self.sut);

    OCMExpect([partialMockSUT loadFollowersForUser:[OCMArg any]
                                         fromOffSet:[OCMArg any]
                                            toLimit:[OCMArg any]
                                withResponseHandler:[OCMArg any]]);

    [partialMockSUT loadAllFollowersForUser:123
                           withResponseHandler:^(BOOL success, id response, NSError *error) {

                           }];

    OCMVerifyAll(partialMockParser);

}

I am using a partial mock because I only want to stub the loadFollowersForUser method and call the actual implementation of loadAllFollowers method. This does almost exactly this but my test always fails to meet the expectation and I see the NSLog in the console.

Things I have tried:

1. I have tried adding other temporary methods to verify the behavior of parital mocks and they perform exactly as expected
2. This question suggests what I am trying to do should be very much possible
3. I have tried adding OCMStub for the method after the OCMExpect inline with OCMock documentation. See 10.2 on this page

I am not sure if its a problem with block being passed in or that the method return type is void and I have no action for the expectation.
