You are correct, I should not have replied to Mark when I had not yet had my morning coffee. The dynamic rendering of OBJECT elements still trigger the HTA functionality exposed in Windows. Personally, though, I see this as an unrelated vulnerability regarding static/dynamic code rendering which has a greater impact than just allowing HTA code to execute.
Both GM#001 and thePulls POC, which malware cites, are one and the same issue instead of two separate, they both trigger the dynamic rendering of HTML instead of the static - GM#001 just does this without requiring scripting.

At the present, the patch for MS03-032 breaks one of at least three
exploit techniques. The patch does not resolve the vulnerability.
MS03-032 acknowledges this. I have seen several examples of this
vulnerability being exploited in the wild.
In particular, the current MS03-32 patch doesn't account for an HTML
document created via XML/data binding:

The patch also does not account for an HTML document created via
script:
