Why does GreaterThan (>) operator on ISSUE field fail on moved issue?

Suppose we have a project AAA with issues AAA-1, AAA-2. If we run JQL query

issue > AAA-1

then we get AAA-2. So far, so good.

Suppose now that AAA-1 has been moved for some reason. Now the same search returns nothing, plus an error message:

"Operator '>' cannot be applied to moved issue key 'AAA-1'.

Is there any reason for this behaviour?
