Enforcing Custody Orders: How Does a Custody Order's Provision for End of Summer Visitation Work

My question involves a child custody case from the State of: Texas

I am having a difficult time understanding the following paragraph and I was hoping you could help. My bottom line understanding is that my ex-wife will have our kids for the entire week before school starts even if my 1st-3rd-5th weekend fall within that week. Is that the correct interpretation?

2. Extended Summer Possession by MOTHER - If Mother gives Father written notice by April 15 of a year or gives Father fourteen days' written notice on or after April 16 of a year, Mother may designate one weekend beginning no earlier than the day after the child's school is dismissed for the summer vacation and ending no later than seven days before school resumes at the end of the summer vacation, during which an otherwise scheduled weekend period of possession by Father shall not take place in that year, provided that the weekend so designated does not interfere with Father's period or periods of extended summer possession or with Father's Day possession.

Thank you for your help
