Reading further down the page it says you have to compile the python code using CPython, then generate binary code for its custom ISA. That's neat, but it doesn't "execute python directly" - it runs compiled binaries just like any other CPU. You'd use the same process to compile for x86, for example. It certainly doesn't "take regular python code and run it in silicon" as claimed.
A more realistic claim would be "A processor with a custom architecture designed to support python".
