viewing isn't an explicit offence under those laws. I expect the reason the website suggests is may be is because the act of viewing on the Internet is itself transmitting (or causing another to so transmit) the document electronically, which is an offence under the legislation (with additional considerations, such as whether it was done with intent to carry out or encourage someone else to carry out terrorism; it's quite hard to prove—or disprove for that matter—intent without supporting evidence, which may or may not include an overwhelming quantity of similar documents). The legislation provides that the accused can offer their politics as a defence against any charges under those sections, by proving that the document "neither expressed his views nor had his endorsement". What bothers me is that it's not the other way around: I'd prefer if it was up to the court to prove that the documents expressed one's views or had one's endorsement rather than placing the burden of such proof on the accused. Of course these are my interpretations and IANAL ;)
