Old Murk-Eye does not summon murlocs when you spend gold in Stormwind Siege.
It only summons murlocs when your ally spends gold. And it doesn’t even look like it’s summoning the correct amount of murlocs. It’s more like it summons 1 murloc for each mini your ally plays.
Same here just played against Allison, he did not pop any Murloc at all 
.
Won anyway, but not much fun.
