DOES "EXTENDED DEBATE" MEAN FILIBUSTER?

I just looked up what happens after the Senate and House iron out their differences and the result is called the "conference report." This may not be amended but in the Senate it seems that the report may be filibustered:

In the Senate, conference reports are usually brought up by unanimous consent at a time agreed to by the party leaders and floor managers. Because conference reports are privileged, if any Senator objects to the unanimous consent request, a nondebatable motion can be made to take up the conference report. Approval of the conference report itself is subject to extended debate, but conference reports are not open to amendment.
