Yeah, my logic too!
When I tried it, it didn't really closed (locked) the backflow preventer valve, and all air went out from backflow valve.
I was running it at around 40 PSI, and was scared to increase the pressure so as not to damage sprintker heads.
Ended up paying someone $60 to close it for me.
I will try my 8 gallon compressor with higher pressure now.
I did observed that the sprinkler guy was blowing air at 100+ PSI, so hopefully it should be safe.
I'm okay with it taking more time for my 4 zones, as long as I know it's working.

That said, I did just fine with my 6 gallon pancake. Instead of 2 cycles for a zone you could get it done in 1 with this 24 gallon unit!

In my case my inbound water is delivered at 142psi +/- (time of day dependent). I do not have any regulators installed, so theoretically I can evac the system at around 120psi. Though I use 100 just to be on the safe side.
The 4.0 SCFM at 90 PSI direct drive with a 50% duty cycle is not great, but not bad and with the 24 gallon tank will be fine for most homeowners and light duty shops that don't depend on an air compressor to run a bunch of volume air consuming pneumatic tools all day. It is direct drive, which means the compressor part is likely steel and not cast iron, so yes, it is an entry level compressor that is a step above the oil free variety.
As far as being Porter Cable, we have been using this model [amazon.com] on job sites for years, but do buy much cheaper than Amazon is asking and bought the last four here on a deal [walmart.com] for $99 each delivered.
Personally, I am done with the cheap 'oil free' compressors that depend on Teflon or whatever for the bearing and piston wall lubrication. Where the larger oil free compressors do seem to shine is with spray painting, but the water and oil separator that most use will resolve that.
