But they say it works. Well.

It will not work.
Please analyse only output stage: IC C+D and output transistors.

Imagine, that you disconnect input pin 10 on C from pin 12 and 7. Now
compute bias current thru Q1, Q2 as a function of voltage between pin
10 and 12. You will see, that gain of this stage is near infinity, any
positive voltage between 10 and 12 will shortcircuit Q1 and Q2.

Now reconnect your circuit and think about bias current as a function
of input voltage offset of D and C. How long will it work?


Good question. Thanks.
