I am going to do a SeaFoam treatment today. Is it okay to do the procedure found in the FAQ, but leave the SeaFoam gas in the car AFTER I change the oil?

Kind of sketchy on the instructions...

those two won't mix so it shouldn't matter.

You can use it three different ways, none of them really interfere with each other. Treat the oil to clean stuff inside the crankcase, treat the fuel to clean the fuel system, and suck it through the intake to clean that.

The issue with it in the oil is that it thins the oil and makes is less effective at protecting your engine from wear, so leaving it in the oil for extended periods is not good.

However, adding it to your gas only affects your fuel system, and unless you've done some really odd mods to your engine, the fuel and gas shouldn't be mixing. You can add Seafoam to your gas whenever you like to keep the injectors clear (just like any other fuel system additive).
