Lefevere said he was watching the race and in the first group of 50, he didn't see anyone from his team.
In the end, someone from the team got 32nd.
That doesn't necessarily mean what Lefevere said is false: you can have a split in the peloton and a group of 50, and sometime after there can be regrouping, as the first 60 riders came (more or less) together across the finish line.
So the most likely scenario is that Lefevere's riders were all caught behind the split, and some made it back into the first group. Lefevere was talking about a moment in the race.
