Meadows only flipped his position on HR 3762 when it was revamped and hardened by the Senate to make a political point to the voters back home.
In other words, Meadows only supported the bill when it allowed him to hide behind the skirts of the Senate version which both they and he knew was designed merely to be vetoed:
[T]he Senate's version would have implemented a two year phase-out of Medicaid expansion and exchange subsidies.
The House agreed to the Senate's changes, so the final version of the bill included the Senate's modifications.
There were concerns in Congress – particularly among lawmakers from states that have expanded Medicaid – that repealing the law would result in millions of people losing their health insurance coverage. But Politico reported that "senators were reminded that the president would veto the repeal bill anyway, meaning Republicans could vote on the measure without having to deal with the political risks of actually making major changes to existing law."
But there are still 206 Republican members in the US House in 2017 who voted for the original, honest HR 3762 in October 2015, and who should do so again in 2017, if only someone (not Mark Meadows, and not Paul Ryan) would lead them there:
The House version of H.R. 3762 included repealing the individual mandate, the employer mandate, the medical device excise tax, and the "Cadillac tax" on expensive employee health insurance premiums.
It also included a measure to eliminate federal Medicaid funding for Planned Parenthood for one year. But it called for increasing funding for community health centers by $235 million/year for two years (a 6.5 percent increase over the currently scheduled funding).
Republicans used the budget reconciliation process to ensure that their bill could advance through the senate as long as it received a simple majority of at least 51 votes, instead of needing 60 votes. By using reconciliation, the measure was filibuster-proof, and advanced to a vote in the Senate.
