Exhaust brakes not needed with auto transmissions?

See post on rv.net.

Quote:

Hey gang.. the reason no exhaust is approved for the automatics is due to heat via torque convertor slippage.. But here is the skinny... An EB is not needed on the auto... They hold the load back when decending long grades... The manuals, however don't...

Can someone explain how an automatic transmission can provide better engine braking performance than a manual transmission?

I keep reading similar post from the Chevy D/A owners who claim that the Allison does not need an exhaust brake becuase it has "grade braking".
