In general, you need not worry about such cases. All deaths are logged, as are the Soul Strand rolls. If you were dead when you logged out, you'll be auto-killed when you log back in. Whether a GM was watching or not, the result would have been the same, and there's really nothing a GM can do to prevent it.
If, by some odd turn of circumstances, there was an additional Soul Strand loss due to logging in and being killed by the system, this would once again be logged verifiable. So again, there is no need for caution or concern. This is not a normal behavior of the system, and as such we would not hold any penalty to you as a result, however unlikely it may have been.
