Al Jazeera English filmed it, and the Israelis were quite happy for them too.
Following the Summer war in Lebanon, Israeli lost some of it's military prestige. It may want to get back it's aura of military invincibility it had in the region by quickly having another more successful war and attacking Syria in some form.
Alternatively, Syria may be planning to attack Israel because it feels emboldened by Israel's performance against Hezbollah, after all, Syria wants the Golan Heights back but from the link you posted, if true, Syria seem to be preparing forward defences, not an attack.
This follows reports of secret peace talks between Syria and Israel.
Perhaps this is a flexing of each other muscles to show each other while they talk.
Edit: Just found this:
Olmert is offering Assad talks
Syria has repeatedly said it wants peace talks, and Israeli officials have admitted that secret contacts have taken place. "Bashar al-Assad, you know that I am ready for direct talks with you," Mr Olmert said. "You have been saying that you want the negotiations through the Americans. But they do not want to sit with you. I am ready to sit with you and talk about peace not war."
also in the link:
Meanwhile, the Israeli press has been full of talk about the possibility of renewed hostilities with Syria, and the Israeli army has been staging exercises in the Golan Heights.
Some Israeli intelligence officials have warned that Damascus is preparing for a conflict.
