Does this bug anyone else?

Whilst reading up on IPsec at Wikipedia, I came across this:

IPsec is implemented by a set of cryptographic protocols for (1) securing packet flows and (2) internet key exchange. Of the former, there are two:

I want to learn about IPsec. I don’t want to be hindered by having to read back over the sentence to remind myself which was the former and which was the latter.

Would it be so hard to swap “Of the former, there are two:” with “For securing packet flows, there are two protocols:” ? I’d find that much easier to digest.
