Chokes wound in parallel on same core

[ŚŚŚSHAD0WŚŚŚ]

I saw some chokes that had three wires bound togetehr at the ends (parallel) and wound five times around a toroidal core. Why would they do that? Doesn't that reduce the inductance? Why not just use one wire?

To reduce skin effect and/or fit a higher current winding in the
winding window than could be done with a single wire.

No

probably a manufacturing restriction, winding machine can't handle the heavier wire, etc.

why do you care?? what's important is the coils' performance
