It does seem like the author is telling you he can read at a rate of one page per 10 seconds. Although, I have a suspicion what he's doing/referring to is the art of 'skimming'. This is a skill similar to speed reading in which the reader 'scans' each line for key details rather than reading each word.
The premise of this is that the human brain only needs to decipher and take in 'key words' in order to make sense of any given text. For example, consider if you were to read the sentence, 'come and see me later', you only need the latter in order to understand what's being asked of you. So with speed reading or skimming you would ignore the first few words and only quickly read the last few.
I often used this method throughout my degree and although it's known as speed reading I think the name is misleading. Rather than using speed what I do is 'chunk' words together as opposed to reading each and every letter. This is a phenomenon investigated in psychology and is used by almost everyone in less concentrated formats. For example, when someone gives you their number you often group several numbers together right? i.e. read the numbers 0,8,0,0 as 0800 as opposed to separately. Or if I were to give you the letter sequence F,B,I,C,I,A,S,A,T, you would be more likely to remember it if you chunked the letters FBI, CIA and SAT together.
Anyway, I digress :P
