Actually I googled between the frustration last night and found a thread where the exact opposite advice was given when it comes to curly negatives.
In general, clipping the corners will help the film enter the spool and help to avoid it getting stuck.
But when the negative is curling up like a metal-coil, the cutting can actually help the film slip out of the reel. It can also be harder to load plastic reels with ball-bearings like that (works very well with 35mm though).

Generally I saw that people advised against it in 120 format and plastic reels with ball bearings.
