I assume you mean a solid connection between the drain hose and the waste pipe. If that were done, then anytime the drain system plugged up and water rose in the pipe above the level of the p-trap connection, water could be siphone into the dishwasher when the pump out cycle was completed. But the air gap can be drained into its own connection.

: What is the difference between draining the dishwasher through an air gap and draining
: into a seperate drain which is backvented into an existing vent line?
