I feel if a gerund is in passive form, a good (correct?) form to use is a possessive like 'his' or 'her' rather than an object pronoun like 'him' or 'her'. Is that just a thought of that can hold no water?
eg.
I feel him being (able to be) in my birthday party is good.
Not good: I feel his being (able to be be) in my birthday party is good.
But, if the gerund is in active form, I feel the opposite.
eg.
I applaud his coming back to our team and playing for us.
Not good: I applaud him coming back to our team and playing for us.
