To be fair, I don't think I've never seen that notation either! I've only ever seen the form 6.67430E-11 ± 0.00015E-11, which is much clearer.
We use it regularly in our experimental data: 6.3(4), 15.002(10). Things would become complex using exponential forms for errors, specially when starting to play with exponents: 6.67430E-11 ± 1.5E-15.
