Sounds like a "space between the ears" problem with the technician,
if they expect that to be a useful way of diagnosing the problem.
You are correct: a blown chip tells you where a problem now resides.
It tells you nothing about where the problem *was* before you
shorted the fuse. It was, after all, a *circuit*, meaning one
thing is connected to the next, and all you discovered is which
component will blow up / heat up / char along the way.

And sometimes when you do that, the dead chips will notify you
of their new condition by blowing their tops.
That is also a sometimmes useful method of finding where the problem
resides.
