That is wrong.

A trap is required so waste gases don't enter the home. If you are not sure if there is one. Remove the laundry drain and flush the toilet, then have the broker go over there and sniff

Re: Air gap for washing machine
No, but an air break is.
Quite correct, what is shown is wrong.
(bold and underlining are mine)
AIR GAP, DRAINAGE SYSTEM. The unobstructed vertical distance through free atmosphere between the outlet of a waste pipe and the flood-level rim of the fixture or receptor into which it is discharging.
AIR BREAK (DRAINAGE SYSTEM).An arrangement in which a discharge pipe from a fixture, appliance or device drains indirectly into a receptor below the flood-level rim of the receptor, and above the trap seal.

Is something missing?
I was thinking an air gap was referring to the faucet on tubs and sinks.
The above only mentions the outlet of a waste pipe.

Re: Air gap for washing machine
They make air gaps for washers, for example:
- VA4 Airgap for washing machine wall box drains - 1/2 CPVC Glue Fitting - FreshWaterSystems.com
... but I've yet to see one installed.

Re: Air gap for washing machine
It (the laundry stand pipe) is also insufficient as to size/diameter (DFUs).
P.S. The hose clamp is serving no purpose at the outlet side of the gooseneck pinned against the wall where gooseneck is improperly connected to undersized laundry stand pipe. It (the hose clamp) should be at the drain hose end securing the washer drain hose TO THE gooseneck.

Re: Air gap for washing machine
Yes, the bolded font for the entire term, and you apparently skipped over the qualifer in the term being defined which JP had modified the font to "unbold" (now "bolded" AND "highlighted" in orange):
AIR GAP, DRAINAGE SYSTEM.
i.e. DRAINAGE SYSTEM AIR GAP.
RC, you're thinking of the potable or supply system "side" air gap, which when "a plumbing system" "air gap" is not further qualified, would include.
Since the OP is from New York State, and in the STYLE of the NYS Plumbing Code the definitions appear thusly note the difference(s):
