Unfortunately it's not a rumour... I'm not able to mention who told me but I can say with confidence he REALLY knows what he is talking about!!!

So imagine my surprise (and, yes, confusion), when it was pointed out to me that the DSP chips found on the HDX cards, while indeed able to execute 64-bit tasks, really are 32-bit processing engines. Meaning that two or more instructions are required to perform 64-bit calculations. Meaning that the available DSP found on the card will be cut in half when moving to 64-bits.

I don't know who told Andre this but I've been told the exact same thing. Look at the dates in that PDF you linked to. The design of those chips dates back to 2006. They're hardly state of the art.
