Is it me or does this sound like someone having a bad hair day?
CPT is hardly the busiest airspace in the world, and I bet it must be really tough having two people flying the plane and share the workload.
Is that second pilot too busy getting their makeup ready on final approach for the R&R stop in Cape Town, and thus too busy to have eyes out side to look for those scary helicopters and maintain some situational awareness?
The heli-ops in CPT are some of the most professional in the world, the training first class, and there is always attention to not scaring the (apparently easily scared) f/w pilots, and working with ATC for separation and noise abatement.
Would knowledge of helicopter holding / crossing / manoeuvring points and procedures at CPT be a benecificial addition to your pre-flight briefing to help understand what to expect when you see rotary wing traffic and trying to anticipate how that affects your situational awareness?
