It is interesting that we are discussing entangled particles.
The argument that quantum mechanics are based on requires a photon to be independent and have random properties.
This limits the measurements which can be taken to one measurement.
In the case of entangled particles there is a physical relation between the two particles and spin of one particle can be determined from the measurement of the other particle.
If the spin of a photon is known by the measurement if its entangled partner then a second property can be determined by measuring the unmeasured partner. In this way two measurements can be taken. Violating the second quantum premise without violating the logic it was based on.

I would say that I think all theory is useful as long as one does not forget the premise it was based on.
If we follow theory blindly we become its slave, and it becomes our master.

Boy that was good, I hope I can remember that one when I need it someday.
