Nope. That is an incorrect statement. I do it all the time. If you capture from satellite, for example, it's 1080p at 29.97fps. If you look at it (and it is an original film source) you'll see that every 5th frame is repeated. Telecining doesn't imply interlaced video. In this case it just represents converting 23.976fps original video to 29.97fps by repeating a frame. It's hard-telecined (meaning it doesn't use flags to create the additional frame). Mixing odd/even fields from two frames of an interlaced source to add an additional frame is one type of telecining -- but not the only one.

Anyway, it's meant as an additional tool for those who need it (like me), not as a focus for a debate on semantics.
