Is the ablution valid if the beard is re-combed after wiping the head and ears, knowing that it was combed after washing the face?

"The ablution of one who suffers from incontinence is undoubtedly valid because the separation between wiping the head and washing the feet by running fingers through the beard is a slight separation that does not disrupt continuity and does not affect the validity of the ablution. The same applies to repeating the act of running fingers through the beard or any other ablution act due to forgetfulness."
