I guess the longer answer is it depends on the analyzer chain of Field 2. As Gora mentions, fields are copied before analysis, so they are re-analysed/tokenized in the destination field. If the destination field has different analysis rules, then those will be applied.
We explicitly use that benefit for some language specific fields, we have a headline field (which uses basic tokenisation, minimal stemming, etc) and headline_en, headline_fr, headline_de, etc which have language-specific analysis rules. Our data is indexed into headline_en, headline_fr (we know the language of the headline externally, so we can do that in our indexing pipeline), and we have a copyField from headline_en to headline and then we have 2 different indexed forms of the same data, one with language-specific rules, and one with a more generic set which we can search separately.
