Which is largely irrelevant to the likelihood of making the connection other than to cover the relatively unlikely scenario (more unlikely than missing the flight) where the OP needs to rely on Connection Saver to hold the second flight.

Also, it's not that UA sells the connection because it "expects you to make" a 55 minute connection, it's that UA's willing to accept the risk it will have to rebook you. That's not much of a risk from UA's perspective, but it can be a big hassle for the passenger, which is why most of us would also be thinking about contingency plans even if this itinerary were on a single ticket.
Sure, agree 100% it's always a good idea to have a Plan B. But the comment I quoted above was effectively take the L now and forget about trying to make it - that is what makes no sense to me.
