Out of curiosity, why does the assignment of a function to a variable output the echoed string inside the function?

I understand functions, how they work, why they’re used, etc. I just don’t follow why the sheer act of assigning it to a variable triggers the echoed string. You’d think that, like the return value, the string would only show when you called the function.

Could someone shed some light on that for me? Thanks!
