am start -n与am stack resize

am start n 一个应用后，调用am stack resize时，应用会重新打开。
有没有大神了解的，为什么会重新打开，应用launchMode是singleInstance。
如何不让它重新打开呢？

am start: start an Activity.  Options are:
    -D: enable debugging
    -N: enable native debugging
    -W: wait for launch to complete
    --start-profiler <FILE>: start profiler and send results to <FILE>
    --sampling INTERVAL: use sample profiling with INTERVAL microseconds
        between samples (use with --start-profiler)
    -P <FILE>: like above, but profiling stops when app goes idle
    -R: repeat the activity launch <COUNT> times.  Prior to each repeat,
        the top activity will be finished.
    -S: force stop the target app before starting the activity
    --track-allocation: enable tracking of object allocations
    --user <USER_ID> | current: Specify which user to run as; if not
        specified then run as the current user.
    --stack <STACK_ID>: Specify into which stack should the activity be put.
