This record is keyed to SEC CIK 0001063663 — the identifier this person files under in their own name. Every vehicle above is a filing made under that CIK, so “the same person on two shells” is a fact about an SEC identifier rather than about a name that happens to match.
Roles are the strings the filings used, in the order they were filed. Nothing on this page ranks them, infers seniority, or offers a reason why any two of these names recur — a recurrence is a count, and the filings that produced it are linked beside every row. We also hold 88 institutional-holder rows on these vehicles, under 48 distinct name strings, and none of them is counted across vehicles: that table has no CIK column, and matching holders by name would merge firms that are not the same firm.
