Depends
The wording in that section of the rulebook (3rd Edition p218):
Each sip of a particular Kindred's blood ... If a being drinks three times, on three separate nights, from the same Kindred, ...
It's vague at best. So we could say:
- No, because strictly speaking it needs to come from the Kindred directly.
- Yes, because it's an inherent power of Kindred blood.
The biggest problem resolves around: how long is Kindred blood in a human considered Kindred blood? Checking Ghouls - Fatal Addiction we come up with no further info, except for:
One vitae is ingested, it passes very quickly (like alcohol) into the circulatory system. Plasma and all, it saturates the interior walls of the digestive tract and quickly finds its way into the veins, back to the heart, and from there throughout the body...
This seems to indicate that the Kindred blood is quickly absorbed into the human, transforming him into a Ghoul (and empowering it). Which strengthens the No case.
The one thing to consider is the concept of Overdosing. If a ghoul is fed Kindred blood on a nightly basis for a month, his human blood will be replaced with Kindred vitae. Feeding from such a ghoul would definitely trigger the Blood Bond.
In reaction to SPavel (tried to answer in comments, but it got too long):
- I doubt Kindred would feel comfortable that one of his Ghouls drinks blood from other Kindred on a daily basis.
- If this is an Independant Ghoul (Regnant is dead or he was abandoned), then following this feeding pattern would mark him as an excellent target for a Blood Hunt.
- With regards to becoming Blood Bond to the supplying Kindred: have a list of names and a d10 ready (technically it would be 10 + Stamina score of the Ghoul, but let's keep it practical). Assuming the ghoul never drinks twice from the Kindred, he will be now have a first step Blood Bond with a random Kindred (assuming that Kindred is alive; there is this rumor that the dead of the Kindred breaks all blood bonds...).
