Although, I wouldn't think hybrids would save much in maintenance costs. Yes, the brakes do get less wear, but there are effectively two drivetrains to maintain, which can't be free.
In any case, their projections about longevity and costs are probably a bit vague anyway, given they were wrong about brake longevity by a factor of two.
The electrical side has no moving parts, which can be very cheap. The ICE side is used about 50% of what a normal bus would use, so that extends its life and reduces maintenance costs.

I wouldn't say the electrical side has "no" moving parts, there are at a minimum, an electric motor or two, as well as some contactors. There may also be a temperature management system. And there is still a physical interface between the two systems, which can vary in complexity significantly.
To be honest though, I have no idea where most maintenance costs lie with any type of bus. For personal vehicles, usually the drivetrain is not a major source of repairs, and instead auxiliary equipment tend to fail.
