Hi Plesa, long time no hear...
Yeah, it looks too easy, but...
That connector is very compact, and isothermal by virtue of that, it is shielded (also acting metal thermal spreader on the outside). Contacts are very close, made of gold plated beryllium copper, very low thermal mass, attached directly to board, being isothermal there... Also SFTP cable is twisted pairs, pure copper, individually shielded with aluminium, that acts as shield and thermal spreader...
Generally, doktor pyta went with making everything as isothermal and low mass as it can be, instead of relying on exotic components. We shall see how well it does, but in his measurements so far, he got double digits nV TEMF..
I don't have equipment at the moment to measure whatever TEMF it makes now.. My crystal ball sees more equipment in my future... Nanovoltmeter would be nice....:-)
What these connectors are not is that they are not low leakage and are SELV only (max 60V)...
I would think it cannot be used for precision measurement of 100 Gohm with 500V..
My use for this scanner is measuring voltage refs (up to 20V), 4W resistor comparisons (up to 10Mohms), and 4W PT100/1000 and precision thermistor measurements. It should do this with less influence than 6.5 digit DMM can see.
That is more than OK for me now..
Of course, I will keep you guys posted.

Sinisa
P.S. This is the connector type..
