Permissions folder/parent folder

Question

I have a doubt concerning the permissions of folders in my operating system course.

Imagine that an ubuntu OS has three users : Lee, Xon, Yugi.

Lee creates a parent folder X, and gives full permissions (rwx) to Xon, but gives (---) permissions to Yugi. Xon goes in X and creates a new folder called Y ,and he gives full permissions (rwx) to Yugi on that folder.

Since Yugi does not have permission on X would he be able to make use of his permission on Y ? (Knowing that a user must have permissions for the entire path to access a folder)

No Yugi would not as he can't even get past X to get to Y. The lack of execution permission on X for Yugi means he can't even do cd into X to access Y
