Yes ... in fact it makes sense for LLtests with errors to be automatically recycled (but only the first time), since the "worst" that will happen is that there will be an early verification. If there are two results with the same residual this is very, very probably correct, even if both runs had errors - this may well happen, at least with some versions of Prime95/mprime, when the exponent is very close to a FFT run length crossover.
