Yes, I have heard this idea.  I do not think it is valid.

If the flood volcanism had been an isolated process of a few
hundred thousand years duration, I might accept this.  However,
the fact that the hot spot that formed the Deccans is *still*
active today, 65 million years later, pretty much proves that
the source was deep in the mantle, and thus actually much older
than the K-T boundary (since it takes millions of years for
a plume to reach the surface from deep in the mantle).

Indeed I think you will find that the *responses* to the article
you site pretty much demolish its arguments.
