That's not a great idea.
There are often problems on cuts that wouldn't be present the frame (or two) afterwards.
Most films that were cut the old-fashioned way (ie: by glueing two bits of film together) will suffer some sort of warping distortion either side of the cut. There's also potential for splice marks, and other gunk that can be accumulated by the physical uneven-ness of the splce.
Cuts can also suffer from mis-cued telecine timing errors, which generally manifest themselves as darkened strips at the top or bottom of the frame.
If a film has been through any kind of electronic processing (especially - but not exclusively - through a standards converter, or a digital noise reduction process), there's a good chance that the cut will no longer be clean: it will be an electronic blend of two or more frames. This often affects all the other frames, of course, but it's obviously a bigger problem where two adjacent frames are completely different.
So, not a good policy. (Although I understand why they'd adopt it - I've used it myself!)
