Correct. Your quoted example is wrong. It should be the other way.

That is totally wrong as you noted. The author of that claim has either
screwed up or
is....  <cough, cough>.

LET and SR perdict that a measurement of the lenght of the object will
be v*dt where dt is the measured time (clock) and v the measured speed.
The v*dt will yield L/gamma in both theories.
