Switch statement returning incorrect value

I have a switch statement that is running a formula but it is giving me a result of $0. If I run the same formula in an if statement I get the desired $46. Why isn’t the switch statement giving me the value of $46 but the IF statement is?

Switch Statement

        switch (true) {
        case ((VS_MTKL.match(/F../)) || (VS_MTKS.match(/M../))):
            VO_HOOK_0 = SoS_HFXD;
        break;
        default:
            var VO_HOOK_0 = 0;
        break;
    }

IF Statement

        if ((VS_MTKL.match(/F../)) || (VS_MTKS.match(/M../))) {
        VO_HOOK_0 = SoS_HFXD;
    } else {
        var VO_HOOK_0 = 0;
    }

The case expression values in a switch are evaluated and then compared as if === were used in an if. The .match() function returns either null or an array, so it will never be true. It may be truthy, as an array is in an if, but that's a different situation.
