Continuously living in the U.S. for 5 years but not before

I asked about those being more than 5 years ago. She said they still need to check if I left for more than 6 months without a reentry permit or travel document and just got lucky.

That was a poorly trained individual. You don't need a reentry permit to retain your green card for a trip of more than 6 months and under a year. She should have said more than 1 year, not 6 months.
