CA Form 593

What is the meaning of the phrase "without regard to the two year time period" on Part III #2 of the CA 593 form? I have owned my cabin for 20 years but only lived in it for 1year. I am in escrow now. As soon as I sell my cabin, I would like to sell my house and take advantage of the IRS Form 121 marital exclusion for $500,000.

Can I check this box to avoid state withholding and still take advantage of the marital exclusion in the same year?
