This is quite incorrect.
See the analyses of WLP001 and WLP013 and WLP023, for example, here:

'British' does not automatically equal 'diacetyl' - usually, in fact, it's quite the opposite
Youre mostly right, Diacetyl is usually a problem with lagers but WLP 002 and Wyeast 1968 (conveniently left out of the links provided) does throw diacetyl when yeast is in poor health or in the wrong temp. range. This yeast is one of the classic English strains and is the yeast I use most often when making English ales. I know some of the other American and English Ale yeast dont produce as much diacetyl as this one.
