It would appear that John B. Henderson has become a victim of auto correction
Apparently DERLD = Delayed Exchange of the Ruy Lopez Differed
which in
Fast Show style, is nice.

A minor curiosity is that delaying the exchange to move 6 is rather more common than "only" move 5.
Presumably it is thought Black committing his Bishop to e7 in the interim makes a significant difference?

I think that was the idea. If DERLD is a possibility, playing the marginally risky move order 5. .. b5 and then 6 .. Be7 is a way to avoid it.
