He most definitely CAN ( = is able to), and the "will" part is the matter of time. Hopefully, the time is now. I think Nole's advice helped Janko a lot, and in return Janko's match will prove valuable to Nole.
If Djoko's advice was hit to the FH not the BH I can safely say that Tipsy would have figured it out eventually. In return Janko could teach Djoko how not to choke on set points
As for the OP the answer is obviously yes, whether or not he will is a different matter
