Think of it this way. If I gave you a paragraph in Turkish (or insert language X) to memorize and recite that's very different than giving you some greetings and responses to memorize and recite.
For the first there is no mental model for where the paragraph fits in or how it's constructed. In the second almost everyone has some experience learning greetings in a couple of languages just by exposure to pop culture, so even if you don't understand the specifics of how those phrases work you have some confidence in how to employ them and you'll generally feel somewhat confident in being able to break them down later if you need to because greetings done in short and simple language.
