Hi!
I'd say, just ignore it - it could be coincidence, or could simply be that because you are getting interested in the techniques, small synchronicities like this are showing up because they match that energy in your life
Worrying about it probably would only serve to fuel a sort of negative energy around it, and as a result to match it his attitude/doubts may get reinforced, which isn't what you want.
While if you simply ignore it, and act like it was nothing to worry about, then it should manifest itself in this direction
Hope it helps!
