No, DC offset is very different to quiescent current - they are two completely separate parameters. You must measure Iq with nothing connected to the output terminals because any additional current that flows in the load will upset the measurement.
I haven't read the whole thread (via the magic of copy and paste: https://www.diyaudio.com/forums/solid-st...ds-28.html), but I see that you did indeed confuse the two in post #273 - you described the voltage across the two emitter resistors as the DC offset, when in fact this voltage pertains to the quiescent current. I didn't read all the subsequent replies, so don't know if things became clearer...
