Windows task fails but throws no errors and writes no output

This creates a task that works and writes to a file:

schtasks --% /create /tn "test" /sc minute /mo 10 /ru SYSTEM /tr "powershell get-date | out-file -Encoding:ascii c:\log.log"

This does not create a log file and i cant see any errors:

schtasks --% /create /tn "test2" /sc minute /mo 10 /ru SYSTEM /tr "powershell someexe --help | out-file -Encoding:ascii c:\otherlog.log"

The second command isn't writing to the log file, why? Even if it fails it should still be writing to the file. If I run this from the command line it still writes to the file:

PS C:\> powershell doesntexist --help | out-file -Encoding:ascii c:\fail.log
PS C:\> cat .\fail.log
doesntexist : The term 'doesntexist' is not recognized as the name of a cmdlet, function, scrip
or if a path was included, verify that the path is correct and try again.

+ doesntexist --help
+ ~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (doesntexist:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

So I cant understand why the first task is writing to a file and the second one is not
