simultaneous detection and length contraction

I find in a leading journal the following title:
How to obtain the Lorentz space contraction formula for a moving rod
from knowledge of the positions of its ends a different times.
My question is:
Consider a rod at rest in I', located along the x' axis. Its ends 1
and 2 are characterized by the space coordinates x'(1) and x'(2). The
proper length of the rod is
x'(2)-x'(1)
independent of the time when the mentioned coordinates are measured.
Is it possible that observers from I measure the coordinates of ends 1
and 2 at different times, taking into account that their clocks read
the same running time as a consequjence of the fact that the clocks
they use are standard synchronized? At each end of the rod we find an
observer from I characterized by the space coordinates x(1) and x(2)
respectively.
