Not quite correct, if I remember correctly dry soil adsorbs more water and quicker (by default) than waterlogged soil. But when is been dry for a long time a hydrophobic film forms, causing a temporary delay in water adsorption. I think it can impact flash flooding, but it washes off fairly quickly and then adsorption returns to expected.
