That was nice...and the right thing to do IMO. I have done that on several occassions. I have told people what pictures to take to prove authenticity, what incorrect information to delete from their ad, and advised a seller of the retail price of a purse they got for Christmas. In the latter case my advice kept them from accepting a low-ball BIN and I wound up winning the bag in the end (because they didn't take my other advice and add more pics). While I think helping out a buyer usually raises the selling price and benefits the seller, it can also benefit a hesitant buyer when they receive additional info or photos. I don't do it expecting anything in return, but I do believe in helping others and in karma. Cheers to you and everyone else who helps out others!
