Better calculation times, conclude to faster Android devices. This way you can also check how lightweight your custom made Android build is. Or not. As Pi is an irrational number, Benchmark Pi does not calculate the actual Pi number, but an approximation near the first digits of Pi over the same calculation circles the algorithms needs. So, the number you are getting in miliseconds is the time your mobile device takes to run and complete the Pi calculation algorithm resulting in a approximation of the first Pi digits.
