Nope, this post is using GLX over the network.
Nope, that's indirect rendering and is limited to OpenGL 1.4 more or less. This is using a much newer OpenGL than that.
Also if you look at the source it's specifying direct rendering in glxCreateContext: https://humungus.tedunangst.com/r/xtoys/v/tip/f/circle.c & https://registry.khronos.org/OpenGL-Refpages/gl2.1/xhtml/glX...
The only thing leaving that process is a pixbuf, zero X11, identical to Wayland.
