Did I fail to understand this statistic Muppet?

" Over the last decade, the number of
new diagnoses among heterosexuals declined in England, especially in London. In 2012,
numbers were highest in London (1,020; 35%) followed by the PHE regions Midlands and the
East of England (590) and the North (400) and South of England (370).
In Scotland, Wales
and Northern Ireland, the numbers of new diagnoses acquired heterosexually were lower, with
110, 50 and 40, respectively (Figure 5). "

I do fail to understand how it is compatible with "Keith says heterosexual transmission is falling but it isn't."
