Question about Symbol / Glyph of Warding

The spells mention: "If you choose an object, it must remain in place; if it is moved more than 10 feet from where you cast this spell, the glyph is broken, and the spell ends without being triggered."

The "without being triggered" part explicitly indicates that this rule is meant to apply before the spells are triggered, and only to the glyphs themselves, not to the effect they trigger. Meaning that if you correctly identify a Symbol trap on a table, then simply move the table 15ft away, it's enough to deactivate the trap. But you can't do so after triggering the trap, right?

With that in mind, if someone activates a Glyph of Warding with Spirit Guardians on a book, and then moves the book after the spell is triggered, the effect should move freely with the book without being dispelled, right?
