That is probably good advice. The issue is clarity for the reader. When two I's come in sequence, the hyphen is often used, but nobody will expect a word with a double I. This is different with a double O or a double E, both of which occur frequently in English. For example a cooperative can be called a co-op. The hyphen is important to differentiate it from coop. If one writes "I live in a coop", it would read as a chicken's house. The word re-emerge might cause a stumble without the hyphen.
