I think this variation must have come from Sun Cunzhou.I can't say I have ever seen lazy man done in this way nor white crane spreads its wings.Some of the other moves such as the deeper golden cock stands on one leg were done by a visiting Sun style master who had trained with Sun Cunzhou but his lazy man was more conventional.I should imagine this was a more earlier version of the form.

I've never seen the Lan Zha Yi done that way either, interesting variation.
