Basic battery switch probably does not have the amp capacity so the inverter may go around it.
Exactly this--and you probably also don't want the additional resistance (and wire length) in the inverter feed circuit, either. It is very common for the battery disconnect to not disconnect the inverter and sometimes a few other high ampacity loads (such as the generator's 12V connection, since its starter motor is a high current load, albeit one of short duration).
Sometimes there are other constant loads that bypass the disconnect switch because the maker deemed it best to not have them interrupted for various reasons. Common examples include propane and/or CO detectors, power entry steps, and radio preset memory power.
