The Required behavior of the nothrow operator new reads:

   This nothrow version of operator new returns a pointer obtained
   as if acquired from the (possibly replaced) ordinary version...

The "as if" requirement implies that any observable effects of
"the (possibly replaced) ordinary version" must be preserved.
The repeated calls to the new handler are among such effects.
