I guess by default the meaning of equal-top and equal-bottom ranking is to rank the candidates equal. The voter may have interest to cast a stronger vote where the equal-top and equal-bottom rankings have some additional strength, but that's another story, and not the default interpretation of ranked votes.

Simplicity. Lack of interest to truncate one's vote (and lose preference information) at the top and at the bottom.
