the post you are responding to, in my intrepretation, was referring to protect the customer in case of a ‘misconnect’, not about bags. Of course agents can check a bag through (how easy the computer makes it is another question completely) on two separate UA reservations. But there is no policy I aware of that requires UA to protect you when you are late from a UA flight on one itinerary, causing you to miss another UA flight on a second one. I’ve only seen reports on here saying they have accommodated, but the point is, it’s not policy and not required. So OP could be SOL if they misconnect.

So unless you get an excellent agent who's willing to go the extra mile with *A partners, expect to be arriving a full day later (on EWR(-SFO)-HKG the next day). Even in the best case, don't expect to be arriving any earlier than ~12 hours late.
