The "\@!" roughly translates as "the atom right before me? It's not
allowed to match at this place". It's zero-width, so the
remainder of the pattern starts matching right were the assertion
would have started. Which is why
"\<\(RCMP\|QEII\|SPCA\)\@![A-Z]\{4,}\>" matches "WASPCAT", because
the disqualified "SPCA" doesn't come at the beginning.

Hope that clarifies a bit.
