The short answer
No. When a saga re-enters with Doubling Season in play, it receives 2 lore counters immediately, which causes both Chapter I and Chapter II to trigger simultaneously on the same turn. Chapter I is not skipped, both chapters fire at once because the lore counters satisfy both thresholds together.

If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.
If an effect would put one or more counters on a permanent you control, it puts twice that many of those counters on that permanent instead.
