My guess it could the third phase of the four rounds of testing (double trains), unless some phases are concurrent.
They took some of the hoarding down and then put it back up again. The ones in the middle of 75 street at Davies station for example. These metal contraption they have at the base of the V looks hideous IMHO (for the brief amount of time it was exposed before being covered back up again).Could be the want to five them a 56-day stress test and leave the wrap up incase there are more stress fissures.
