Yes, that would have been me who cautioned against getting two puppies so close to age or from the same litter. The bonding issue with humans is just one concern that can happen. As Corgimom noted from the PWCCA site: "most reputable breeders will not sell you two puppies from the same litter because the puppies most likely will be more bonded to each other rather than to you. It also said that the more dominant puppy will inhibit the more submissive puppy." I'd also advise against getting two females.
For the most part, dogs don't really need canine "friends" - the humans become their pack. IF you get the second puppy get it because YOU want the dog, not because you believe you are fulfilling some need in a dog. I'd suggest reading some of the thread started by Woogiebear about the trials and tribulations
of having two young puppies.
What type hints or things the breeder did that made her seem reputable? I'm only asking this for informational purposes only and because it might help someone else in their search for a breeder and a puppy.
