Short answer: They do! Read this article on how to count rotated symbols.
Long answer: Because of the way construction drawings are designed, symbols will often be rotated through a number of different angles.
For example, because they’re located on different architectural walls, it’s common to see socket outlets rotated through 4 or more different angles.
In the clip above, you can see 4 different rotations of the double socket symbol. When multiple selections are made, those 4 symbols (and all similar looking sockets across the project), are automatically counted.
