Question about the Love Scene in the Pool

What do people think was the timeline for Marlee Matlin and William Hurt characters their first night together?

Hurt goes to visit her swimming in the pool (presumably late at night). He eventually falls into the pool and the two of them surrender to their feelings for one another, making love quite passionately. It's a very romantic scene--sensual and tender all at the same time (the characters clearly had a lot of pent-up feelings for one another, and in fact Matlin and Hurt started dating during filimg)

The next thing we see, the Program Director is arriving at work in the early morning and sees the William Hurt character dashing out of the pool to his car clutching some clothes. The next scene, Hurt is summoned to the Program Director's Office to find his shoe that he had left on the pool prominently left on the Program Director's desk.

Do we think that the Matlin and Hurt characters are supposed to have made love in the pool the entire night until morning, when they realized that they had to scurry out of there in a hurry? Or do people think that they had sex, then fell asleep outside the pool, and subsequently had to scurry out?
