Positioning a ESP32 Module on a Base Board

[Partokus]

Hello! I use ESP32 WROVER-B. Sorry for my english.

Found in "ESP32 Hardware Design Guidelines" (page 10) recomendations for position of esp32 on board.

Tell me please why 3, 4 position highly recomended? It is because to the right of the esp32 do not recomend place any components? I am wanna know because i want tightly place component for smaller sizes of my board.

It probably is highly recommended because the antenna connects there, which indicates that the RF Unit is also placed somewhere on the top right of the ESP Module.
So when placed on the corner of the PCB theres no other component around which could induct signals into the antenna/rf unit

Thanks! So, if it because of antenna good working then i can please to the right of the esp32 at least connector of UART for programming because i use it only for programming and it will not disturb wi-fi's working.
