This 'specified set of coordinates' needs to be specidied, too. 
Therefore, we need another set of specified coordinates to specify the 
previous ones.

And so on and on, with infinite regress.

He could have used 'mumble' also (instead of 'inertial coordinates').

Contrary to your view, you need a starting point for a position vector. 
And that starting point needs also a vector, which defines, where that 
point is located. (and so forth...)
