The same could be said for IWB carry (especially Appendix Carry), don't you think?

If you're pocket carrying with no pocket holster, possibly... But I believe Most of us pocket carry in a Pocket Holster and when reholstering, many remove the holster from the pocket, holster the pistol, then place the holstered pistol in their pocket.

Another rule for Pocket Carry, especially if one is not using a Pocket Holster, is not to have ANYTHING else in the same pocket as the pistol, so nothing gets bound up in the trigger guard that could trip the trigger.
