Yes, that is by design.

The main purpose of the global mark is that you can use it to easily 
reorganizing code.

First you set the global mark to the place where you want to move some code.

Then you successively "mark and move" various pieces of code to the 
global mark (and advance the mark).

Typically, while doing this, you would want to add some "separation 
text" between the pieces of moved code, like whitespace, commas, or 
newlines, and that is why "self-insert" is remapped to insert at the 
global mark.

Quirky but useful :-)

I guess we could make an option to disable that specific feature of the 
global mark.
