I have started skimming through the paper. I am uncertain if the below text is correct? > Throughout this paper we will use the terms *input script* to refer to `w= itnessProgram` and `scriptPubKey`, and *output script* to refer to the `wit= ness` or `scriptSig`. Figure 2 contains to what looks to me like a `witnessProgram`, `scriptPubKe= y`, or `redeemScript` but refers to it as an "output script": > OP_IF > 10 OP_CSV > 2 As Bs 2 OP_CHECKMULTISIGVERIFY > OP_ELSE > 2 Au Bu 2 OP_CHECKMULTISIGVERIFY > OP_ENDIF > > Figure 2: The output script used by the on-chain update transactions.
