120 Hour Survival Question

I some-what understand the 120 hour survival requirement, per Texas estate code.

I understand that if you died intestate, and say your children would be heirs to your property, and one of them do not survive you by 120 hours, then their heirs would be entitled to this.

One scenario that tripped me up, and I want to be sure I am correct. If you have separate property, and you die intestate (no children) - but your spouse dies 2-3 days later (less than 120 hours), in the eye of the law, did you technically die a widow - and your spouse’s family line would have no claim to the 1/2 he would have inherited?
