The first confusion addresses a requirement by BIP141 which necessitates a two-byte push towards the number 40. This point emphasizes a particular technical detail within the Bitcoin Improvement Proposal (BIP) 141, highlighting its specificity in terms of coding requirements.

The second area of confusion pertains to the equivalence of OP_TRUE and OP_1 within the context of Bitcoin's scripting language. There is a clarification that moving forward, references will be made to OP_1 instead of OP_TRUE to enhance clarity. This shift in terminology aims to make the intended functionality more apparent, possibly because OP_1 directly indicates the boolean value true in a more explicit manner compared to the traditional OP_TRUE.

These points collectively shed light on the intricacies involved in Bitcoin programming, particularly in how specific operational codes and proposals are understood and implemented. The emphasis on clarity and specificity suggests a continuous effort among programmers to refine and optimize the coding practices associated with Bitcoin transactions and scripts.
