Atomic here means the data operation is performed by a single assembler instruction,

add dword ptr[esp+0x20], eax

Because it's needless, nearly all its methods simply wrap other methods (e.g. Int32.Parse). It offers no benefit and adds an extra method call.

It's more a matter of style, discipline, and clarity of thought.
