As in the phrase "I don't plan to retire for another few years"
This is completely anecdotal, but I find that when people use this type of phrasing it generally means that they'll revisit a decision at a later date, but it's not imperative that the matter be decided upon right now. By phrasing I mean anything along the lines of:
I'll know if I'm going in a few hours.
I don't plan on moving until my kids are out of school in another few years.
Again, these types of phrases indicate that a decision must be made in the future, but it's not important for the moment at hand.
In the context of your question, I'd say the individual has obvious plans to retire, but the action of making the decision to retire will be delayed by several years for what I suspect is a variety of reasons.
