Do you think the following quote describes accurately a more realistic and/or harder to fool lie detector test than the standard one?

Describes a TV series. Quoted almost word for word:
”‘Alias’ features a more realistic lie detector—that is to say one that doesn’t explicitly say “Truth” or “Lie”, but just provides raw data such as heart rate and blood flow in particular areas of the brain, requiring the interrogator to use his own judgment to decide on the truth of a given statement, and being much harder to fool. Then, outright subverted, when the difficulty of tricking the device almost gives away the protagonist, when after extensive training and practice with her handler her results look too perfectly honest during the real interrogation.”
