I think the relevant issue is you could conceivably have a house with two outlets with opposite phases. Bussing them together in the PSU will then create a short

> two outlets with opposite phases
This is actually THE standard in the US, which is actually fundamentally a 240V power grid but with an electrode stuck halfway down the secondary winding on every pole transformer, which becomes your "neutral". The two ends become L1 and L2, so that L1-N is 120Vrms, L2-N is 120Vrms, and L1-L2 is 240Vrms, and this is what goes into every home.
The power outlets connected to L1 are all opposite phase to all the ones connected to L2.
Rather than bussing the two outlets together, what you can safely do is get an electrician to just wire up an outlet with L1 and L2 and voila you have a 240V outlet. This is how you get all your dryer outlets, EV charging outlets, electric stove outlets, etc.
