I technically have 3 jobs, two unrelated "full-time" SE roles, and 1 mom&pop store where I handle all but day-to-day operations (handled by the gf).
To be cold bloody honest, unless you are SE for a serie-A start-up a 40h weeks is probably 20h work, 20h bs. If you were SE for a serie-A start-up, a 40h week would probably be 80h-paid-20h anyway.
The biggest hurdle is the morning scrum, I've got two pretty much back to back between 10am and 11am. Other than that, both are relatively flexible and there is not much critical meetings which can't tweaked.
I’m curious that any Tech company allows multiple full time employment. All tech companies require employees to sign work for hire intellectual property assignment. You must disclose any other intellectual property agreements with other entities.
Even taking on a side job contract has IP issues. Most companies claim full ownership of any IP produced by employees at any time, on any devices.
There’s also workman’s comp and medical insurance, unemployment insurance and all other issues that conflict with multiple full time employment.
I know people that work full time and do a side gig. Either their own business or a part time under the table contract job.
I’ve never known anyone work multiple full time SE jobs. That leaves easily discoverable paper trail.
Why do you think he's concerned if they "allow" it or not? The paper trail is not as obvious as you think. The insurance issues you note are not a real problem.
If, for example, he needed to decline health coverage at one employer he can simply say he has it through a partner. It will not be questioned. The workers comp and unemployment insurance won't matter. Multiple jobs are normal for many folks and the payroll companies and government won't care.
