The point is it's not the same situation as having a second pilot ordered after the first pilot was rejected by the very same people, which was the context of the conversation above.
I believe the show was "rejected" by CBS, the same network which later approved the Dick Van Dyke version. The original version was shown in 1961 as part of an anthology series called The Comedy Spot
. Happy Days
followed a similar path. It's original pilot was shown as part of Love American Style
imdb ( yeah I know) has this write up:
The pilot tanked, but the network liked the concept, so it was rewritten and recast with Dick Van Dyke playing the lead role, Mary Tyler Moore as his wife and Reiner as the bullying series star Alan Brady.
