I think here she gives us (unintentionally?) a brief glimpse into why chicks will gladly accept help from guys who they have no intention of fucking.
This is not just chicks.
[disclaimer: I did not watch the video you linked to]
The day after Boxing day, one of my neighbours from a few houses away brought around a desert she had spent some time making, surprising me totally and utterly.
If she had been paying attention, then about a week previously I had mentioned that some visitors were coming round the following night and I was unsure about what to serve as desert, I had given her a brief overview of the rest of the menu. I only remembered this afterwards, desert in hand.
What she brought around complimented the menu very well and would keep in the fridge for a day or so.
Did I accept this help she offered for my entertaining of friends? hell yeah
Do I have any intention of fucking her? nope
Does she know that? yup
Did she walk away with a big smile on her face? yup
