Relationships in the teen years rarely predict relationships in the adult years, so even if Sam and Freddie date now it doesn't mean that they won't both be single again. Maybe they'll decide the tension that built up between them was really just a lesson that Sam needed to grow as a person, and after they learned to respect each other they return to a healthy friendship. In that case, if Carly had feelings for Freddie later Sam would likely support their relationship and it wouldn't be too awkward that they've both dated him for a longer period. While this may not be something that gets screen time...it is still a possibility to consider in your mind for the future we're not going to be shown.
