Subtitled: What are you afraid of?

There's a woman I work with (or maybe two) who, when she uses the toilet, does not actually sit on the seat when she pees, judging by the evidence left behind. Instead she "hovers" her lily-white arse at least an inch or two above it and appears to make circular hip motions to ensure the seat is fully covered in her lovely urine. She seems not to notice this and walks out without wiping it off.

Now, if I go into the toilet after Hover Woman (whoever she is) I'm treated to a bad case of wet butt unless I notice before I sit.

Why do women do this? How is it more hygienic for anyone?
