I don't think anyone is saying it, but lots of people are adding projects on their resumes just because they were in the vicinity of team colleagues working on it.

I actually had someone say something close to that in an interview for a sysadmin position. The guy claimed he had experience configuring Cisco routers.
For this particular job configuring routers was not a primary task, but because I had a passing knowledge of Cisco routers I asked a couple of questions since he had brought it up. After 2-3 questions which the candidate couldn't answer, he finally admitted that his experience in 'configuring' Cisco routers consisted of plugging the network cables into the port at the back.
I once interviewed someone whose resume said he had "modified the Unix kernel to support [some device]". I assumed that meant that he'd written a device driver, but when I asked him about it, he explained that he'd bought a third-party device driver and installed it on his local system.
