Singapore Customs amend stragetic goods form (1)

According to the Singapore Customs e-mail news (Singapore Customs: Updates to Strategic Goods Control Website - 19 Aug 2010), their web site is updated to show amendment of various application form. The form page is in below URL.

I looked through these forms, and find one interesting point.
It is in Annex A - Product Questionnaire A-1 Cryptography, which is questionnaire form of classification of encryption product.

In page 3 of this Annex A (Section C: Functionality of Product, question a. and b.), there are questions a.) and b.) to verify whether the product is "Ancillary encryption", which is exempted from Category 5 - part 2 in Wassenaar dual-use list.

But my understanding is that Strategic Goods (Control) Order 2010 (effective from 1 Apr 2010) don't yet reflect Wassenaar 2010 dual-use list which contains Ancillary encryption Note 4.
I looked through the Singapore list again, but I don't find Ancillary encryption Note 4 in Singapore list.

Why Singapore Customs introduce Ancillary encryption question into their classification application form? Are they implementing Ancillary encryption actually? or just for anticipating the future Strategic Goods list change? If any of the blog reader know, please share your idea.
