Interesting study, but there are any number of ways to interpret the results. An increase in the number of sexual partners doesn’t necessarily indicate that physically aggressive men are any more appealing to women - other possible explanations that I could see include:
- their relationships are shorter lasting than usual, hence there is more opportunity to transition through more partners throughout their lifetime
- they are more assertive in initiating contact with women then other men, which could mean they have more partners through sheer number of attempts
- they could be more willing to press the boundaries of consent in order to have sex (may be less willing to take no as an answer)
- they may be more likely to exaggerate the number of sexual partners that they have had
All of those could explain aggressive men having more partners without women being any more attracted to them, I believe. I have only read the article you posted and the abstract of the linked study, so I am not sure if the study itself attempted to address any of these possible explanations.
