In page no. 105 of ncert underhead topic Bond Enthalpy where its written

My question is, the value of dissociation enthalpy changes from 502kJ/mol to 427kJ/mol in water molecule.The change is due to some change in chemical environment as stated but according to you Sir , the change is because when first O-H bond breaks the second bond gets weaken. Is my interpretation correct? Please explain the ncert paragraph in a little less complicated way. Thankyou Sir.
