scriptSig elements order in HTLC success tx

[hieblmi]

I am trying to understand why the order of elements in the scriptSig of the HTLC success transaction is the following(remotePub|localPub|preimage):

although the HTLC output locking script expects the order remotePub|preimage|localPub:

What am I missing?

checkmultisig checks signatures in the same order as the supplied pubkeys, like so: 0 remotesig localsig 2 remotekey localkey 2 checkmultisig
