However, there is no current input character; all the state machine has done so far is look ahead. Shouldn't it simply emit the two character tokens and switch to the data state?

When the content model flag is set to RCDATA or CDATA in the close tag
open state, the state machine is supposed to examine the next few
character, and if they match the last start tag, also examine the next
character to see if it matches whitespace. If these conditions are not
true, then it is supposed to "Emit a U+003C LESS-THAN SIGN character
token, a U+002F SOLIDUS character token, and reconsume the current input
character in the data state."
