You are right it wasn't perjury, it was "intentionally false' testimony which got him disbarred.

  Judge Susan Webber Wright of Arkansas said Clinton gave "false, misleading and evasive answers that were designed to obstruct the judicial process".

In finding that Clinton deliberately lied in the Jones deposition and his written answers to questions posed by her lawyers, Wright ordered Clinton to pay "any reasonable expenses, including attorneys' fees, caused by his willful failure to obey this court's discovery orders."  

That cost him an extra $90,000 above the $800,000 he had already paid Flowers.
