One set of CTs you described is mounted so primary current is entering the H2 side of the transformer. This makes the X2 terminal "polarity" on the secondary side. The manufacturer must adjust the wiring so the current flowing out of the X2 terminal will flow into the polarity terminal of the meter or relay. The CT H1 terminal does not have to be turned toward the source for the CT to operate properly. The secondary wiring can be adjusted accordingly as you pointed out. You cannot re-mark the CTs physical polarity, even on paper.
The manufacturer would have a standard way that they mount their CTs for comformity, that does not always make sense to end users. The installers are not electricians, so simple rules are adopted. Some customers will specify that all their CTs be mounted a certain way, the secondary wiring must be adjusted accordingly. This is done when the order is placed.
If the diagram in question shows current flowing into the H2 terminal and the X1 terminal is connected to the polarity input of a relay or meter or vice versa there may be a drafting & wiring error. The instruction booklet for the device will normally show a typical wiring diagram. Many of the manuals are on-line. It is the electrical polarity that is important. The CT can be turned either way to get the same results by reversing the wiring as you said. If the relay is a 32 Reverse Power, then current flowing into the polarity terminal will trip the breaker. It may appear to be wired incorrectly at first look, because the non-polarity is wired to the polarity terminal of the device.
Our rule for installers is to turn the H1 toward their body and install. The diagrams show the H1 toward the breaker on both the line and the load. The secondary terminal wiring is adjusted to reflect this.
