That's what it is- a pressure test of the LP system, just like your gas company does before turning on the gas at your house. Testing connections with soapy water doesn't cover everything, such as a leaking valve on an appliance.
It's a point-in-time test and a good start with a new-to-you trailer, but something could go wrong the day after the test. For that reason, instead of repeating the test, I would spend the money on an LP detector.
