It does not need to be cut, just wrap it around itself on the insulator
side.

I was having a discussion with another ham about dipoles and dipole
lengths, and a rather silly question came up that neither one of us was sure
of the answer. If a dipole is using INSULATED wire, can the electrical
length be altered by just wrapping the ends more or less around the antenna
wire when attaching the end insulator? Or does the INSULATED wire need to be
cut? He thinks it does shorten the dipole, I say it doesn't. Hope he is
right, it makes 'pruning' dipoles a lot easier.

Thanks
