It's just less than optimal airmanship fuelled by lack of understanding (although motives may be pure).
If you look at over-run accidents, I think you'd be hard pushed to find one instance where an extra 30 m would have mad a difference. It's the same as an approximate 0.4 second delay in abort decision at 150 kts.
As others have said, if you're that tight on tarmac, don't take an intersection - that's where airmanship comes in, not by trying to milk extra field out of an already accepted reduced length.
