I'm not Japanese but I train here and teach Tomiki Aikido to Japanese and others. A lot of effort was made to translate Tomiki's writings into English and these are available at the web
page of Shodokan Honbu (Tomiki's own dojo). The explanations are extensive.
It is clear from the text you quoted that the person has only passing familiarity with Tomiki Aikido. All I am advising is that you go as close to the source as possible rather than a friend of a friend of a friend.
