StringSplit IsArray problem

[confucion]

$high = "E"

; ### Validate: $high ###
$tmparr = StringSplit($high, ".")
If IsArray($tmparr) Then
  $Invalid = 0
Else
  $Invalid = 1
EndIf

MsgBox(64, "Found", $Invalid, 3)

Please run the code above.

Why is the msgbox result displaying 0 when $high clearly doesn't have a period (.) in order to split it into an array?

[guinness]

In the Remarks for StringSplit it shows that @error is set to 1, but it will always return an Array.

$high = "E"

; ### Validate: $high ###
$tmparr = StringSplit($high, ".")
If @error = 1 Then
  $Invalid = 0
Else
  $Invalid = 1
EndIf

MsgBox(64, "Found", $Invalid, 3)
