Does the tool check for case sensitivity?

By default, exact matches are case-sensitive. 'Apple' and 'apple' will be treated as unique lines.

Does it sort the lines after removing duplicates?

No, it preserves the original order of your lines. The first occurrence of a line is kept, and subsequent duplicates are removed.
