The Bitcoin Script engine would evaluate this script as follows:
1. +R+ is pushed to the stack
1. The OP_SHA256 operator takes the value +R+ off the stack and hashes it, pushing the result H~R~ to the stack
1. +H+ is pushed to the stack
1. The OP_EQUAL operator compares +H+ and H~R~. If they are equal, the result is +TRUE+, the script is complete and the payment is verified.
2. The OP_SHA256 operator takes the value +R+ off the stack and hashes it, pushing the result H~R~ to the stack
3. +H+ is pushed to the stack
4. The OP_EQUAL operator compares +H+ and H~R~. If they are equal, the result is +TRUE+, the script is complete and the payment is verified.

1. OP_EQUALVERIFY pops H and H~R~ and compares them. If they are not the same, execution halts. Otherwise, we continue without output to the stack

1. OP_CHECKSIG pops +<Bob's Sig>+ and +<Bob's Pub>+ and verifies the signature. The result (TRUE/FALSE) is pushed to the stack.

As you can see, this is slightly more complicated, but now we have fixed the HTLC and made sure only the intended recipient can spend it.
