[libreoffice-users] ReDim of a variable of a custom type

I was, in a reply to another question, told that my questions were way
too basic for the dev@api.OpenOffice.org list, so I'll give it a try
here instead.

I wrote some example code:

REM  *****  BASIC  *****

Option Compatible
Option Explicit

Type MyType
       a As Integer
       b As Integer
End Type
Dim x(1) As MyType

Sub Main
       Dim y As MyType
       Dim i As Integer
       For i=0 To 1
               x(i).a=1+i*2
               x(i).b=2+i*2
       Next i
       y.a=5
       y.b=6

       MsgBox x(0).a & x(0).b & x(1).a & x(1).b & y.a & y.b ' Displays 123456

       ReDim x(1) As MyType
       ReDim y As MyType
       MsgBox x(0).a & x(0).b & x(1).a & x(1).b & y.a & y.b ' Displays 123400
End Sub

So if we have an array as MyType (or any other custom type, I
suppose), ReDim will not reset it.
Is this the expected behaviour or should I write a bug report?
If it is expected, why?

I guess it's unnecessary to mention that I am a complete beginner in
everything that has anything to do with computers; we guitar players
are quite stupid, you know.

Oh, and in case it matters:
LibreOffice 3.3.3, Ubuntu 10.10.
LibreOffice installed with the debs at http://www.libreoffice.org/.
