pinan yondan is all about meotode, irimi and nagasu
Pinan Yondan is the fourth Kata from the series. According to Kazumasa Yokoyama sensei, Pinan Yondan is an advanced version of Pinan Shodan. I have heard on many occasions from different instructors that apparently Ohtsuka sensei would always ask a student to show Pinan Yondan during a grading.
Pinan Yondan, the fourth Kata from the series of five emphasises Meotode, Nagasu and Irimi. Kake uke is in Pinan Yondan, as opposed to Kake uke from Chinto, Jitte and for example Niseishi executed as Morote Uke in a somewhat forward movement. Especially the second Kake Uke involves forward movements, which is called Nusumi ashi, meaning to steal the distance.

key points of yokogeri and empi
here's why and how to perform yokogeri
It can be argued that "originally" there was no talk or specific instruction that it should be Yokogeri. However, if a certain method is better than the other... what should be the obvious choice? Now I don't know who or when it was decided to officially call it Yokogeri AND to place emphasis on it — but I do know WHY it's better and WHAT you should focus on to create higher quality movement.
The skill you develop is EXACTLY the same as in Naihanchi.
Hirate Uke to Uraken contains two key elements
Dynamics of the elbow and Yosei Ashi Dachi
Second is the dynamic of the elbow, which is quite sophisticated in Pinan Yondan. Subtle maybe a better word. Here's what to note when you perform Tate Uraken.
applications of hirate uke
Hirate Uke from Pinan Yondan and Kushanku can be used more or less directly in combat. It's proven effective against a front kick as well as stabs. Here's an application that closely resembles the Kata.
Hirate Uke is an excellent example of how to practise Taisabaki in Kata. It's the reason why we use a wide stance AND why it's a side way movement. This footage is from summercamp 2010? where I demonstrate many different ways to use and practise different applications.
