This type of comments are used generally when writing code for a project/software package, since it helps to generate a documentation page for reference, which can be used for getting information about methods present, its parameters, etc. However, if these number was arrived at as a result of an intentional effort to reduce the line count of methods then you might have ended up with a single logical task being spread around several private methods which will make it more difficult to understand the class (in certain cases).
