Certainly not. The output of a regulator is somewhat hashed and reflects the common supply at a smaller scale, usually within 5% (depending on the mosfet quality/price).
When setting up a PSU one puts a R+C (resistor+capacitor) behind to 'smooth' the signal some more, and mainly to prevent power spikes at switch on/off. Usually the R is way over 1Kohm so adding a <1ohm wire wont change anything to this. Besides a R+C will not change the total voltage...
And i suspect your very PSU has this R+C for quality reasons.
