It could be picking up on secondary elements that they're experiencing which are true, and confirming that.
Empathizing with the person when validating the validation target is extremely important.

Validation of feelings is vital to connecting with others.
If you're like most people, you probably feel that you are quite adept at validating others. We all know how to validate someone with whom we agree.
However, where validation skills are most valuable is in dealing with situations where we disagree or are in conflict with someone.
We may be reacting and resentful ourselves to a lack of being validated. In a "BPD family" there are going to be validation issues.The mutual validation of feelings is important in all phases of relationships including building, maintaining, repairing, and improving them.To validate someone's feelings is first to accept someone's feelings - and then to understand them - and finally to nurture them. Invalidation, on the other hand, is to reject, ignore, or judge. Let's say one family member has very high validation needs, or one member is invalidating, or both have high validation needs, or both are invalidating?In these situations, it can be difficult to find something to validate while remaining true and authentic to ourselves.It can be even more difficult to find the motivation to counter our own emotional instincts and our proclivity to reject, ignore, or judge.
