The "coax" is not normal 50 ohm coax... on high performance/high frequency probes.
It is usually a kind of "lossy" coax, which uses a shaped mono-filament resistance wire for the center conductor. That wire is somewhat brittle (compared to copper)... and shatters or cracks... when bent, mutilated, or stapled.
Usually if you buy a high performance probe for a song...without testing it... the song you might end up singing is from the blues.
Clueless sellers tie them up like the ribbons or bows on a Christmas presents... often using twist ties.
