Somewhat. They're still significantly more efficient than ICE vehicles. Regenerative braking adds 10-25% efficiency on it's own.
The study behind your article has this to say on the issue:
> The share of kilometers that PHEVs electrify results in a total of 15%–55% less tailpipe CO2 emissions compared to conventional cars. This is much lower than expected from type-approval values.
So certainly worse than indicated, but still better than alternatives.
